If anyone gets a boat with a built-in belly tank be sure to check it real good. At the shop where I work I'm working a 1992 Mako with a rotted out aluminum tank. I must have done about 5 other tank replacements within the past 2 years, all the same problem. Water getting into the tank, fuel leaking out, saturated smelly foam having to be dug out - a real nasty job sometimes. Below are a few pics from today. First of the tank after the floor panel was removed and the top of the tank cleaned off of grime and other unknown organisms that had been growing in there. The second showing the one hole in the tank I was able to find, right next to the fuel pickup connector. And third emptying the tank into water jugs and other portable fuel cans. The first jug I filled on the left was ALL water, 5 gallons of it. The second jug on the right at that point was half water, half fuel (fuel being the yellow liquid on top, water on the bottom). In all I had to drain out 62 gallons, 7 of which was water. We'll be replacing the tank with a poly tank of approximate size to fit in the compartment, we're not doing a custom sized tank on this job.
-
WOW! I hope the tank in my CVZ is in better shape than that.
-
Rich,
I can't help but notice that the percentages match what you'd get with phase separation. Was that boater running ethanol fuel?
-
Rich,

It's all ethanol blended fuel around here. I don't think you can get non-ethanol on the east coast.. Not sure what you mean about phase separation though. ???
-
The blended fuel will absorb water until it reaches a maximum concentration then the fuel separates into the alcohol water mixture and the gasolene. The maximum concentration is temp dependent so in cold winter temperatures the amount of water before phase separation is only a few onces per 10 gallons of blended fuel. The fuel will not reblend. What you pumped out of that tank matches the 10 percent ethanol plus water.
It's been a huge problem here with the vented fuel systems.
In an outboard set up the oil stays mixed with the gas so if you suck the alcohol/water solution there's no oil lubrication.
-
What I pulled out of the tank was recent. I siphoned the water out of this tank a couple weeks ago but then we had a lot of rain. That's where the new 7 gallons of water came from.
-
Looks like you would be OK ...
From Merc manual ...
-
While talking built in fuel tanks, what are CVX tanks made from? Are they subject to rotting out like the alum?
-
The tanks in the CVXs are mounted high and dry. It's tanks like the one in my Searay that sit in the keel of the hull that can corrode from the ouside in due to laying bilge water all the time.
My anecdote for ethanol blended fuels is this. I've never witnessed phase separation with ethanol fuel or known anyone that has. I pumped 3 year old gas out of my wifes snowmobile after I couldn't get it started( which has a vented tank) and phase separation still hadn't occurred. The gas looked and smelled good so I put it in the tank of my GMC and burned it up. I ran our pontoon boat for 2 seasons on same tank of ethanol blended fuel. That gas was 18 months old by the time I put fresh gas in.
I suspect most issues with water contamination in fuel systems have absolutely nothing to do with ethanol blended gas. Boats like my CVX18 were built with water separator filters when ethanol fuels didn't even exist. What does that tell you.
-
I'm with Kip. Ethanol is an easy scapegoat when in all likelihood it had nothing to do with it.
My CVZ tank, which I know never saw an ounce of Ethanol gas in it, had quite a few pits, and even a corrosion hole in it from sitting in the floor. Looked exactly like the ones pictured here.
-
Ok, now i am curious! I think I will be pulling the tank out of my CVZ as soon as I get home tonight. I gotta know the condition of it after reading this post.
-
The damage to the tank Rich has pictured looks like to me the damage was caused from water outside the tank, being brine or salt, I've not seen that kind of deteriation from water being in an
aluminum tank, how ever much it contained, water seperates to the bottom of the tanks, just my 2 cents. I've had a lot of boats with aluminum tanks, a few with 200 / 300 gallon aluminum tanks in the belly, salt water use, and one I had in Galvaston Tx. had two 400 gallon aluminum tanks that had been in there 20 years, and there was some corrosion damage to the outside of the tank, of which I grinded and coated with epoxy tank liner coating. Two of the house boats I've owned had aluminum fresh, and grey water holding tanks, I didn't have any problem with those ?

Scapegoat? I don't think I was blaming ethanol for anything. I was only pointing out that the amounts pumped out of that tank were in the percentages of what I would expect from a phase separation. Phase separation does occur, I've seen it but have not suffered from it. 10 percent ethanol would have been 6 gallons in a 60 gallon tank and depending on the temperature would probably take somewhere around a quart of water to cause phase separation.
If there was 7 gallons of water in that tank, the ethanol should have separated from the gasoline and blended with the water for 13 gallons of non gasoline liquid.
The water causes the phase separation.
All gas has some additives, so to some extent some water can probably be absorbed in any modern fuel. The water separator filter may do a fine job of removing water droplets, but is worthless against a phase separation condition. Ethanol fuels have been around a very long time. Long before Art Carlson or Bob Hammond were born.
Personally, I think ethanol blends are bad energy policy and a waste of food product, but I have never "blamed" ethanol for fuel going stale.

You know, I think we have this topic on ethanol come up at least once a year.

I don't believe I called you out or anything...reread my post....where did I state that YOU were blaming Ethanol? Ans. No where.
Relax, I made a general statement based on all the fuel issues blamed on Ethanol across the internet.
I know I didn't deserve that response though...and yes Brandon, we've been here before...

I saw this coming...... There is really two completely different topics going on here. I think somewhere along the line there was a misinterpretation. I don't think anyone thinks the ethanol caused the corrosion.
-
if there in no water introduced to the ethanol blended gas, there would Not be a phase seperation, that was not the problem in the tank that adressed in this post, even the underground tanks at the filling stations are vented.
Ethanol has some issue with the early production seals and gaskets not designed for the ethanol, it does act as a drying agent for rubber and some gaskets, plastic tanks, etc, but most of this stuff has been generated to accept the ethanol, but if you don't introduce water to it, it don't seperate.
It's been a problem for yard equip, small motors, and such in the past, but like Doran said, it's been around a long time, not so much a problem any more, think Alcohol, we have all put tha in our tanks to absorb water.
The water seperating gas filters we have today, on our boats, are great, OEM, they have a shield kinda like a chamois skin inside then, water will absorb into the shield, but gas will pass thru it, when the shield is totally absorbed, it stops the gas from entering the carb, kinda neat, but some of the aftermarket filters don't function like that. Gasoline will run right through a chamios skin we dry our cars and boats with, but water will not, it absorbs that, like the water seperation gas filters do.
-
The original idea of the post was to show a tank replacement as part of my duties at the shop, and why the tank was being replaced. Corrosion from being in a wet enclosure along with a marine environment caused the tank to rot out, not the ethanol. I was also showing that water was entering the tank from rain, and just how much was getting into the tank from the holes that were created because the top of the tank was causing water to build up on its surface. That's about it. Wasn't intended to be a discussion on ethanol at all, but more of a constructional thread.
-
Had issues with my Z belly tank, nothing terrible, just corrosion from rotten stringers and all. Cleaned and sealed up the corrosion, then sprayed bed liner material over it to form a shield to prevent future water issues. As for fuel use, I never leave fuel in tank over winter, and change filters every year. Never had an issue. My tank rot was from the outside, not the inside.
-
That oil leak is indicative of a bad shift rod bushing seal but can also be from pitting around the shift rod where it sits inside the seal. Have the seal or rod replaced.
-
The gear oil is going to expand when hot and leak out when you use the boat, therefore as the oil cools water will be drawn into the gearcase. I would be very cautious.
-
What do you think Rich ? Could it be the lower seal in the upper gear case, thats what the little leak is I think, on a boat I'm looking at, bearing worn, making a little whine running on the water hose, can't hear it in the water, just a small leak, table spoon over the winter.
-
Diamond Chad posted a pic of the gearcase of a Merc outboard, which uses the same (or similar) shift rod seal & bushing as an Alpha One. When there's gear oil coming out of the front cavity drain it's usually from the shift rod seal. I've changed a few and have the special tool to replace it.
-
Getting back to the original subject - the tank was pulled from the boat finally and more holes were found near the original hole. They are marked in yellow in the bottom pic.
-
Rich
Have you been replacing these with plastic or aluminum again?
Do you have much of a problem finding a replacement that fits?
-
We've been replacing them with custom made aluminum tanks, but they are epoxy coated to prevent corrosion. On this particular boat we're going with a ready-made plastic tank rather than a custom one.
-
After building the tank for Gary's boat out of fiberglass, I am Not anxious to build another one, just Too much time and expense, and yes, I coated the tank with epoxy, steel flex, but I have since learned that I could buy an aluminum tank, already built to to spec's for les money, I don't think
I'll do that again.
Many of my response's I make to post here are, maybe, based on phone calls and emails ...
Auminum tanks are my preference, but poly tanks are good, just Really expensive to get one
made to your own spec's.
Listen to Rich, he's the guy in the business.
-
Shipping $ may be an issue (they're out of FL), but this place has a vast supply of various sized tanks;

(Okay, I admit I'm a "Ship Shape TV" addict!)
-
The new tank went in the boat today. A lot more room in there compared to the original tank. It was a real bear getting the old fill and vent lines out because they ran under the port-side console, but once they were out running the new hoses in was easy. It's all plumbed and foamed in. All that's left is to add a couple of cross braces and install the floor panel and seal it up.
-
That whole job musta cost a pretty penny.
I bet you love your job most of the time. That is great!
-
I like working on the engines mostly. I hate ripping out old gas tanks especially when it involves nasty stinky slimy waterlogged foam and unknown organisms. Funny thing about this boat is we sold it last August as a used boat and knew back then there were problems with the fuel tank so I think the shop is picking up some of the tab to have it redone for the customer who's been so patient with us.
-
Finished! Cross braces are added and the floor panel screwed back down. We had some rain so I had to vacuum out the water before setting the floor in.
We've got another one coming in possibly next week, same model boat, same year, looking like it will also need a tank. Oh boy!
-
Nice job Rich.
-
Great work Rich!
I you know what your are doing fir sure:)
-
Oh boy!!!!!!
Guess what I get to work on at the shop. Just came in today, another gas tank replacement in a 1988 Mako Center Console. The boat I thought we were getting for a tank replacement this week hasn't arrived yet, and this one showed up. So maybe this will be a regular thing. One a week?
Already got it uncovered. Tomorrow I get to remove the gas/water and dig out the foam to pull the tank out.
-

But you do such a great job at it...so folks keep letting you do it..lol
hows that 4.3 conversion coming along?

Well like the stuff I regularly end up fixing at work at least it pays the bills. Might not be the most fun but regular work is better than no work at all.

I just wish this board had a scratch-n-sniff app so everyone could experience the same thing I do when I work on these tank replacements. ;D

I believe you on the smell, it has to be gut wrenching at times. Probably like the feedlot tractors we get in our shop out at work. Just the look of that tank makes me think what a slimey stinky mess that would be.

lol I remember those things. I'm not sure that I would want to scratch-n-sniff app for that, but one for Gas and oil Mix would be good, for some reason I like that smell

We've had perhaps 2 or 3 more gas tank replacement jobs come in within the past 2 weeks. Check out this one - swiss cheese tank:

Rich, you do work on engines, and stuff too, don't you? lol just messing with ya
how is your other project coming along?

Haven't worked on it this week. When I do I post the results right away in the thread so the last update was the last time I was on it.

cool... getting back to gas tanks. The tank in my boat still has gas in it, not a lot, but some...I think it is a poly tank, any recommendations on how to drain it, and clean it before use? which obviously will be a while
-
Easiest way would be to siphon it out through the fuel line but if you want to get to the very bottom of the tank with a hose then remove the fuel gauge sender and go in through there with a hose and an outboard primer bulb to suck the remnants out. Just need to remember when reinstalling the sender that it only fits back on in one direction, the screw pattern is not symmetrical like the bolt pattern on your car or trailer wheels.

thanks Rich. I will be getting to that tank at some point before the fuel turns to varnish, thank you for the heads up on the re-instillation of the fuel sender, and screw pattern:)

Grows on you. Pungent yes. Reminiscent of skunk ...
I kinda like it. Makes great weed killer ...
-
There's a tank in there somewhere. This is probably the 5th tank replacement we've done this season. I had this one done and wrapped in just over 2 days. There is another much bigger boat sitting at the shop with the console and tank removed since early summer, the customer hasn't contacted us to let us know how he wants to proceed and we can't get ahold of him, seems to be abandoned. :o
-
That's nasty...
seems like a bad design
-
Look what came into the shop today. This is probably the first Glastron I've seen here, a 2010 GT180 with a 150hp Evinrude E-Tec. My job was to replace the Tilt & Trim unit on it with a new one, some electrolysis was attacking the old one so the customer is having it replaced under warranty. Apparently he leaves it in salt water during the season. Also discovered upon connecting the laptop computer to the engine that it had a bad fuel injector on cylinder #5 so I replaced that too.
-
Started a new season at the shop at the beginning of the month so it's back to the grind, and looky I get another gas tank to replace.
On a lighter note we just got in our first new boat pre-rigged with a new Evinrude E-Tec G2.
-
I'm certain those are awesome motors…
And maybe I'm just too old school, but I think they're ugly
-
Technology isn't pretty ...
The E-TEC's look good. the G2's not so much ...
Old school look great !
-
I love that merc look (says the guy with nearly 3 complete omc outboards for a single boat)

Progress on the latest tank replacement job. Old tank is out, found the hole that was letting water into the tank. New tank is in, fastened down, plumbed, and wired. Setting the floor in tomorrow and sealing it up.
-
I dunno if you know this but the reason the G2 cowl looks strange is because there's a ATM machine inside ...
-
I think this makes #3 this year, not sure though because I lost count after #1. Tell ya what though I was having fun with the battery operated Sawzall to get through the foam. In the final pic you can see all the holes in the tank, like Swiss Cheese. This one was particularly nasty, there was so much goop and unpleasant odor and soaking wet foam it was making me feel sick. Whenever I do these I keep thinking about those old "Blob" horror movies and hoping nothing is going to ooze out and engulf me.
-
That's pretty gross !
I imagine the smell make it even worse ...
-
If I had to describe what it smells like the closest I could get would be like a lot of vinegar with a touch of ammonia and old gas blended together.

Sounds like what happens to me after eating Italian sausage ...?
-
We finally got the replacement tank in for this one and I wrapped it up in a day. Here's the tank going in before connecting all the plumbing and strapping it down.
-
Are those aluminum tanks?
Reminds me of Doran's
-
The ones I'm removing are aluminum, the new ones going back in are poly tanks from Moeller.
-
The new tanks will likely outlast the rest of the boat.
-
Well, there's your problem!
-
Wow, what did they hit ?
-
I have no idea, but they hit it hard enough to invert the cone of the torpedo and push it into the gearcase. Cracked the side of the case as well.
-
Fairly certain they lost the drive lube, but if the gears and assembly are intact, is it possible to limp it home that way, or will the water help contribute to the demise of the lower gears?
-
They were able to drive it back home. The boat is at my shop and the gearcase was pulled off and is sitting on a stand in the shop. I've removed the bearing carrier and looked inside, surprisingly the gears are intact. We're waiting on the customer's insurance rep to come and inspect it. He'll most likely get a new lower unit.
-
Direct hit on a rock, or something solid !
Looks like the skag is still attached, hard to tell from angle of picture.
-
Most of the skeg is still there, but the whole pointed end that faces aft is broken off.
-
Just needs a good buffing right?
-
Another season started at the shop, been there since the last week of March and already have tons of work piling up. Many engine repowers scheduled and this nightmare job. This is a 28 foot Mako center console that's getting completely redone, all aluminum rails and T-top piping are getting powder coated, the outside of the hull is getting a repaint, two brand new Evinrude G2's are being installed, and the gas tank is getting replaced. The tank in this is 175 gallons and is just over 8 feet long. Needless to say is wasn't easy pulling it from the boat. We used our crane to hoist it out.
-
Hard to believe it holds that much fuel given its appearant dimensions. Will the new one be poly? Curious is that a head in the first picture?
-
The new tank will have to be custom made from aluminum to be similar in size and capacity. It's about 8 feet 4 inches long, 35 inches wide and about 18 inches deep.
Yep, that's a head. The console has an entry door to go inside for private time. All the white hoses in the hull are drainage hoses for the compartments but the thickest one is for waste transfer to the holding tank down in the aft bilge. When the gas tank was pulled out you can smell the sewage and it's nasty!
-
Yikes, sewage? Probably not the high point of the job. An old plumber friend told me you need only three rules to be a plumber. Poop flows downhill, payday is Friday, and never chew your fingernails.
-

The three rules I was taught were slightly different:
Instead of don't bite your nails, it was "The boss is always right".
And I member you were considered a "Master" Plumber if you could snake a toilet with one hand & hold a sandwich with the other ...
The boss is always right
-
Gee Rich, you're turning out to be the tank replacement king. Between last season and this one you ought to have a good supply of old tanks for recycle. I know scrap prices are down but even at .58/lb you will at least be able to buy a cup of coffee.

While at the shop today we were asked to go look at someone's boat because he said it was stalling and wouldn't idle, also to check the bow light because it wasn't working. I think the customer needs to focus on more serious problems. We had a good laugh from this. LOL!
-
OH MY! :o
-
I tell ya that made it worth going to work today! ;D
-
Any idea what he hit? Story?
-
Don't know. We think there were multiple parties involved and the owner didn't even know about the gearcase 'damage'. That's what happens when you lend out your boat.
-
I would have thought there would be far more destruction to allow the propshaft, gears, thrust bearing and what not to find their way out of the case. Looks like the skeg just got ripped off the bottom.
-
From the gaping hole in the bottom of the gearcase I'd say the rear of the skeg broke inwards and upwards impacting the carrier assembly and pulled all the guts out while traveling aft.
-
Wouldn't idle?
How about, wouldn't move? lol
-
I was wondering how he got back to the dock. Maybe engine exhaust through the open gearcase pushed him? ;)
-
This showed up at the shop last week. From what I understand the owner was still able to drive it back to port with the guts hanging out of the gearcase. :o
-
They must of felt a little vibration.
-
I also get to work on the local Police boats
-
Hey...I meant to ask you this the other night.
What ever happened to that Marina that a developer tore down and didn't build it according to the deal for the land?
-
It's still in litigation, nothing has been done to the property yet. Recently the developer won a battle to proceed with plans to develop and put a much smaller boat yard and marina on the site and put hotels, condos, and shopping on the property but the DEEP (Environmental Protection) have filed appeal on the case because the land is supposed to remain water dependent use and the demolition of the original boat yard was illegal. So it'll be dragged out in the courts for years.
-
The customer thinks he hit something
-
In this case ... The customer is always right !
OUCH !
-
I clipped a wing dam in MN, tore the skeg off and damaged a orop, and it felt like the whole tail of the boat came off. I can't imagine how that must have felt to tear the whole lower unit off. Curious, must have been shallow water in order to retrieve the drive?
-
It was a 'flats boat', sort of like a bass boat meant to go fast. The engine was a recent Evinrude E-Tec 150 mounted high on the transom and on a hydraulic jack plate. The gearcase was torn completely from the leg but I think was still held attached by the shift rod. The whole engine was replaced as there was too much damage. This is the engine:
-
Time for my yearly update at the shop. Been doing several fuel tank replacements, engine re-powers, the usual stuff.
This boat came in sometime last week. Looked like a bomb went off inside the gearcase, it done blowed up! Punched a hole in the side. I opened it up and there was metal debris everywhere inside. YUMMY!
-
Just get some JB weld.. 8)
-

Must have wanted a cheap, quick jet conversion

. I can't say I've ever seen lower unit lube turned into black grease. Must not have seen regular maintenance?
-

Prop shaft was bent and twisted, so they hit something at some point and kept using it. Some damage must have been done internally that just escalated through continued use.
-
So whats a better outboard Mercury or Evinrude Etec?

So whats a better outboard Mercury or Evinrude Etec?
I'm not up on the current Mercs so my answer would be biased seeing as I work for an Evinrude E-Tec dealer. But either will fail just like anything that is abused through usage.
- my politically correct answer for the day. ;-)
-
This got towed to our shop earlier last week. The general consensus is he hit something. He even managed to crack his transom all across the top edge from one side to the other.
-
OUCH !
-
Looks like the hit to the lower unit was quite high preventing the motor to tilt fast enough to absorb the shock, hence the transom absorbed enough of the shock to crack it.
-
JB weld lol

He was cruising at a good speed and hit a submerged rock/reef. Trim units don't tilt on impact, even though they claim they're supposed to. The prop/gearcase is what's pushing the boat and when there's an impact that gearcase is going to get damaged no matter what and damage will most often transfer to the transom. Here's an instance of a light impact, the gearcase is still going to be ruined.

Here's a new one. An new Evinrude E-Tec 200 with only 70-something hours on it. Blown cylinder and engine seized. The top of the #5 piston and inner surface of the cylinder head are cratered like the moon. The customer was just driving out of the no-wake channel when it seized up so he had to be towed back in to port.

Are those pieces of ring on top of piston ?

I think so. But it's so strange to have happen to an engine with so few hours on it. There's one small fragment stuck to the head of the #3 piston too. One thing I've seen happen to several of these engines is the reed valves tend to break and get ingested but usually nothing bad comes from that and I just replace the broken reeds and send them on their way. But something catastrophic happened here.
I believe BRP will be sending us a replacement power head covered under warranty.

one of my pending projects soon, good read Thanks! ( or tanks? )

I don't envy your task. I must have replaced about 7 or 8 tanks this season at the shop. ;-)

Ever see a piston explode into shrapnel? This is another first for me.
The engine is a newer Evinrude G2 300, the number 6 piston shattered and seized the the crank. There was one small hole in the side of the block about the size of a quarter from the debris. When I pulled the intake and reed plate off I was treated to a pile of shrapnel inside. BRP will be replacing the power head under warranty I believe.
-
Thought it was weird getting shrapnel in intake ?
But there fuel injected, so guessing intake is wide open to reed block.

It's direct injection, the injectors spray into the tops of the cylinder heads. But whether it's direct injection or throttle-body injection it's all the same between the reed plate and the cylinders. They're all open through the crank on 2-stroke engines but the cylinders are isolated from each other.

OK .. Understand what your saying ..
What a mess !
