Title: CV23 Exhaust: Yet another thru hull exhaust thread...
Post by: Hot Carl on April 12, 2011, 11:41:38 PM
Under intense pressure from Shrom (just kidding bud), I'm starting the CV23 thru hull project thread a few days early. This is inherently repetitive, as I'm using a lot of the same parts that Jeff, Craig and Shaun used, all successfully, but they are getting tossed in a 23 instead...that's the big curveball.

Jeff, the nicest guy ever, is helping me pull the engine, measure and cut holes this coming Sunday, and it seems like we should be able to get the majority of the work done in one day. The only piece I don't have yet is the new t-stat, which I won't be getting until next week from mooreperformance.

Here's a quick list of the parts I'm using (I'll add more pics throughout the week):

"Lightly" used Mercruiser center-rise manifolds (ebay score)
Mercruiser "S-Pipe" kit (same kit as all three guys used)
10" Tips with internal mufflers from mooreperformance
Alternator Bracket from BPI
New (center-rise style) T-stat from mooreperformance.com
 
It's been a long winter watching Jeff, Shaun and Craig pull off the conversion flawlessly and I can only hope my boat turns out as nice. Thanks again to all of you guys for posting the info and pics that you did!

Here's a shot of the engine before I removed the manifolds and hoses:
(https://lh5.googleusercontent.com/_GdLeShdZlPs/TaUnxqdFG9I/AAAAAAAAAHg/UTS1eP7NMEE/s640/IMG_0170.jpg)

Since then I have taken off both manifolds, all of the cooling hoses, mounted the new alt bracket and alternator and cleaned up the motor.

Basically it's all ready for Sunday...

I can Hear it already !
Lets gather all these thru-hull conversions up under the bridge at Red Wing, point em down the river and open em up all at one time ... I get a 200 ft handicap ... call it a Carlson Blast !

My thoughts exactly...hopefully it'll go quickly with both of us working on it.

And yeah, the Red Wing meet is gonna sound a lot meaner this year... 8)

Shrom - would you mind posting a pic of how/where you mounted your starter solenoid? I think I know where I'm gonna bolt mine up, but would like to see how you mounted yours.

Thanks...

Hey hey, what you have been waiting for finally begins! I would like to just point out that those s pipes should have been mine, but it worked out better cause mine that you found me were a great deal cheaper :P. And I will have a picture poster for you by tomorrow.

Alex,

Great to hear your getting started! What I did with mine was drilled out the bracket that it is mounted on and put it on the rear manifold bolt (solenoid facing the motor).

Shaun -

Thanks man I'm really excited! It's about time I got this started, huh?

Regarding the solenoid, that's pretty much what I planned on doing. I've already drilled out the old bracket; I just have to wait and see how everything fits with the new manifolds in place. I'm interested to see what Craig did too...

Rosscoe - here's an ebay link for the t-stat from mooreperformance if you haven't found it yet:

And the only reason my engine seems clean is because it was delicately preserved by a 1/4" of grime 8)

Thanks for posting that pic of your starter solenoid Shaun - I'll be getting that mounted on Sunday....which can't get here soon enough  >:(

Just for the hell of it, here's a shot of the manifolds I got on ebay (obviously I'm not using the elbows). Not bad for $155:

(https://lh4.googleusercontent.com/_GdLeShdZlPs/Tam8bmEoW1I/AAAAAAAAAII/JSU2J5yQRfk/s640/IMG_0510.JPG)

And the tips/mufflers I got from Dennis Moore...I went with muffled tips to take the edge off of the notoriously loud db levels produced by thru hull exhaust, but I doubt the muffled tips will make that much of a difference.
 
Not the best pics but...

I was pleasantly surprised by the build quality of the tips - the only thing I wish Moore had was a sound clip of the tips in action for those interested in buying them.

The muffed tips will make a huge difference to tell the truth. I had baffles for the Basset Headers on the old flat bottom I had.  I loved the sound with the baffles out but would most always get gigged for excessive noise when I ran without them ... which I usually did!

First off Chris, that flat bottom is awesome :o

I just want it to sound good at idle and not be so loud that no one wants to ski/tube behind it...hopefully these tips proved to be a decent choice.

And considering how loud the cars were that I've owned and built over the years (mostly from the 70's), I really can't believe I want something to be QUIETER? I must be getting old... :'(

Sold it to a friend of mine who wanted the engine for a hotrod project.  Wish I had not given in to him but he made me an offer I could not walk away from.  Been looking off and on for another pretty much ever since.  Was not a good lake boat but sure was killer on the rivers!!! In and out box only.  Idle was moving unless you shut it down and shifted out.  Fun but a bit scary.

Sorry  .. hijacking your thread .. back to the 23 through hull talk  ;D

Alex those muffled tips look great! They have a nice beefy/substantial look. Almost too pretty to cover  up with the flappers. Funny they didn't have some type of a decibel rating on them. For $25 extra a side not a bad investment IMHO.
Title: Re: CV23 Exhaust: Yet another thru hull exhaust thread...
Post by: Shrom CVX-18 on April 17, 2011, 05:28:05 PM
Very nice! looking great man. Those tips will look good. Not sure yet whether I am going to put my external flappers on or not. I have internals. I want to just to be safe. But it def looks better without them on. ;D

Post by: Rosscoe on April 17, 2011, 08:09:31 PM
Those tips look awesome! I think you made a good choice. After all, yours is a CV23 made for cruising. You might want to have a conversation while boating.
Manifolds look nice for the price too. I wonder why someone took those off?
Title: Re: CV23 Exhaust: Yet another thru hull exhaust thread...
Post by: Hot Carl on April 18, 2011, 12:53:02 PM
Rosscoe - the manifolds were taken off a wrecked boat with low hours. I couldn't believe they went so low on ebay. Shipping cost more then the manifolds!

And thanks for all the compliments on the tips guys - I think they look pretty good installed (yes, even with the external flappers)...

(https://lh6.googleusercontent.com/_GdLeShdZlPs/Tax4tiHrxSI/AAAAAAAAAIk/fNE9rv8Q7Ow/s640/IMG_0579.JPG)

As you can see, Jeff and I were able to get everything done yesterday...we got the outdrive off, lifted the engine out, took out the y-pipe and installed the block off plate, dropped the engine back in, measured and cut the holes, permanently installed the tips, bolted up the new manifolds and buttoned everything up. And we only had to run to the hardware store 3 times..that ain't bad at all! Now I just have to mount the starter solenoid, fuel-water separator, and install the new t-stat and cooling hoses and I'll be done.

(https://lh3.googleusercontent.com/_GdLeShdZlPs/Tax4p-xfZ0I/AAAAAAAAAIg/Gya3nmfiSfk/s640/IMG_0580.JPG)

And when I use "Jeff and I" - that's a misleading statement. Jeff took the reins and did a lot of the work and I can't stress enough how awesome he is - Jeff's one hell of a guy and knows his stuff.  

I didn't take many pics of the process; most of these parts are identical to the ones the other guys used, and it all goes together the same. The good news for anyone trying to do the conversion is that these Mercruiser S pipes work great with our boats - we had to move a couple things around to make it work, but nothing even close to major - it's a very straight forward install.

I can't wait to hear this thing run with the new pipes - I should have it finished and running by the end of the week. I'll post some more detailed shots when it's all done and cleaned up...

Big, big thanks to Jeff

 Great work man! I would have to agree Jeff helped me out too, the email he sent me with the steps involved to do this project was right on. All of you guys helped me out greatly. I would like to say thanks also. :)

Alex your right those tips look great even with the flappers on. With your tips being longer then mine you can still see the chrome. Are your tips going to be above water line? Keep up the good work. Glad I could help you out.

No, I didn't have it very long.  Ran it a dozen times or so.  Un-known to me I was bidding against a friend of mine here who REALLY wanted the Hemi.  Get used to it?  Ya, kind of.  Each passenger I took out in it only went on one ride though.  One was enough for them!  I really like the way you could kick the cave plate up and punch the throttle and it would LEAP out of water even at about 30 mph.  I took my buddy who bought it for a ride as he wanted to see the engine run .. he asked me to punch it ... darn near lost him!  I had the wheel to hang on to, he didn't have anything but the sides of the seats.  Was fun while it lasted!!  I'ld love to have another one but finding another with an old-school Hemi set up the way that one was would be hard to come by I imagine.  I bought if for $3200.00.  Sold the engine for nearly double that.  Kind of wish I would have kept the hull but I was looking for a metalflake Carlson!!

Thanks man - we had to pull the engine to remove the y-pipe and install the block off plate. All the other guys that did this conversion (with mercruiser drives) had to do the same. Really it's just a pain in the a$$ seeing that it takes about 2 minutes to remove the y-pipe and put the block off plate in...but ya gotta do whatcha ya gotta do.

And thanks Red - hope you've had time to drop the new engine in the Scimitar!

I still chuckle at the trouble we go too, to make a small change that we want in our boats, and I think I'm about as bad at it only a few.

( It's 9:02 am  168 moments of silence as we remember the bombing of the federal building here in Okc, and the 168 lives lost )

and Nope ... I haven't gone back to work on my boat yet,  trying to be responsile and get other people's boats out first, and it Sucks. 
                                  ;)

I been hooked up Really short on this little woody, but it's coming along pretty good,  be ready for the motor next week. and Besides ... there Ain't enough water in our lake to launch my boat .   Grrrr ...

Looks like AZ a couple years ago.  When This pic was taken the water level was down nearly 50 feet from high water.  This is Lake Pleasant north west of Phoenix.  The lake was enlarged with the construction of a new dam about 20 years ago and they built a new marina near the new dam which is down river about 1/4 mile from the old dam.  They had to blast a channel through the old dam that year so the marina could operate and  the new dam could continue to produce power.

All the snow this year and its still pitiful as are most of the lakes by me. Not as bad as White Bear. Whats it take...a month long non stop rain? I dont even want to go out on the lakes anymore and thats ALL I ever used to do. White Bear is notoriously rocky too, from what I've heard. Never been on it for that reason.

Post by: Hot Carl on April 28, 2011, 11:46:02 PM
Alrighty so I figure it's time for an update...

Last weekend I got the starter solenoid and fuel/water separator mounted, charged the batteries and got her running! I'm VERY happy with the tips and the sound of the exhaust running on muffs, and think I'll be just as pleased with it in the water. The engine's runing good and smooth, I'm not leaking water or fuel = good times had by all.

(https://lh4.googleusercontent.com/_GdLeShdZlPs/TbpA7JpdpOI/AAAAAAAAAJE/CECdltagv94/s640/IMG_0193.jpg)

So that's all good news...now the bad:

I've got an issue with the cooling system, more specifically, the starboard side of the exhaust. Running on muffs at idle, the engine starts to overheat if I let it run for 12-15 minutes. In one instance it approached 190 degrees at which time I shut it off (that's the hottest I let it get). If I bump up the RPM's to 2K for 30 seconds it's visually obvious the impeller is sucking up more water, and the temp will slowly drop. This all seems to suggest that my impeller is on the way out (it's over 2 years old) and I plan on changing it. But wait, there's more... :o

I've got a good amount of water coming out of both tips, but a heavier flow comes out of the port side. Also, the starboard riser is a bit hotter and a decent amount of steam comes out of the starboard side tip. By decent, I mean an unusually large amount of steam. Today I noticed that, after start up, it took at least one minute longer for water to start coming out of the starboard side exhaust. Again, I eventually got pretty good water flow through the starboard side, but that delay can't be good.

My question is could a failing impeller be the route cause of these symptoms?? I was thinking the starboard manifold or riser might also be plugged, but it seems I eventually get solid flow through the manifold/riser.

Two points of potential interest: the port side runs cool and never expells any kind of steam.  The starboard side of the engine sits higher (by at least half an inch) vs the port side, so an insufficient supply of cooling water (compliments of the failing impeller) may inheritely travel to the port side(?)

I talked to Jeff and we both agreed that the impeller needs to be replaced...I'm just looking for any other thoughts in light of this excessive steam issue. Thanks again all :)
Title: Re: CV23 Exhaust: Yet another thru hull exhaust thread...
Post by: OleRed on April 29, 2011, 12:28:21 AM
I'm glad you like the sound,  I'm anxious to hear them, sometime's I like for mine not to be so loud.  I don't know why really, but the port side always seems to get good water flow berore the starbord side does, and I do know this,  the impeller pushes up more pressure that a garden hose, and if the impeller is failing, as you indicated, there just simply may not be enough pressure to give your motor a sufficient circulation, just changing out that impeller may solve your problem, I think so anyway.

The port that service's the risers have the path of least resistance, it's a constant flow, first, the other ports that service the manifolds have to go through the motor first, and the port side head is closer than the starbord side,the first one to get water, only a small amount of water gets around the thermostat to flow through the logs until the thermostat opens.

Post by: Shrom CVX-18 on April 29, 2011, 03:54:47 PM
Looks great man! Mine is the same way the port side flows water out first. I don't you have to worry about it. As long as decent amount if water flows out both sides your fine. I will be getting my new t-state setup on this weekend. So I will be running it again and will have to see if it does the same as yours. We both have the same setup. The one difference is I just put a new impeller in mine last weekend.  :) If the water level is done at the river I will be talking her out for a shake down run. 8)
Title: Re: CV23 Exhaust: Yet another thru hull exhaust thread...
Post by: Rosscoe on April 29, 2011, 07:01:13 PM
Looks great! Hopefully a new impeller solves that issue and puts it to bed.

I have a question and especially since you CV is taller at the transom then many. Were you able to pull your motor with a portable engine hoist or do you have an over head one? My engine hoist will not go high enough to get my motor out. It is about 53" high. Now of course the nose can go up some and I could take the tires off. Setting it on the axel would give me another 5" of so. Just wondering. If I have to have an overhead, then thats another issue, that I dont need.
After looking at the pics closer, yours really isnt all that tall.
Title: Re: CV23 Exhaust: Yet another thru hull exhaust thread...
Post by: Hot Carl on April 29, 2011, 07:07:23 PM
Yeah the more I read into it the more this seems pretty normal. I'm gonna replace the impeller to be safe and throw it in the lake as soon as spring decides to comes back...

Craig - hope you can get your rig in the water soon! It's been hard to catch a decent streak of good weather, let alone a solid day of good weather  :'(  

And Red - it's still pretty loud  ;D At idle it sounds great...the muffled tips seem to take the edge off of higher RPM's, which is exactly what I wanted.

Were you able to pull your motor with a portable engine hoist or do you have an over head one?

Ross - we used a portable engine hoist Jeff borrowed from his work. I could've been a bit more specific when describing the process - we couldn't actually lift the engine OUT of the boat, as the hoist wouldn't go that high. Also, we had to take one of the engine covers off, had to approach the boat from the port corner, and rigged the lift so the arm could extend long enough. Needless to say, we had to screw around with it a bit before we could get the hook over the engine. Once we did get the hoist in position, we only lifted the motor up and moved it about 2 feet to the side. From there we had enough room to work. You might be able to do the same, but it sounds like your boat is a bit higher than mine. I can measure the height of the rear for reference if ya like?

Based on my discovery of a cracked block today, it needs to come all the way out.
I'll likely need to invest in an equalizer as well.

Theat's a bummer Ross. It's like if it wasn't for bad luck, you wouldn't have any luck at all.

There a song about that.....
Yup and the tranny on my truck started slipping moving the 175 in and out of the shop. I'm not even going to ask, what next? Opps, just did.

Ross - I know I'm late to the party, but I'm really sorry to hear about your misfortune  :'( Most of us have been in your situation before and it's never fun. It's always hard to tell if the seller was honestly naive or just a lying pile of crap...hell, the guy I bought my boat from told me the floors and stringers had all been replaced...not a chance. But he seemed "nice" so I figured I could trust his word.

It's a cliche thing to say, but try to make of it. I think Jason mentioned the convenient fact that 350's are some of the cheapest and easiest motors around...I've got a few trustworthy buddies that may have a couple collecting dust, or know of a quality place to source one if you're interested. Keep looking forward buddy...

Sorry not trying to steal your thread, but I contacted a couple of Marine mechanics thru Craigslist that state they have over 30 years experience and their rates are 1/2 what I have seen. I'm looking for someone that will work with  me as I have to save $$. I have a spare 350 as well.
I'll safely say "lieing pile of crap" because they told me they had it out recently and with 2 frost plugs out and cracked block, there is no way. I could tell that oil had not been run thru more the a few minutes.
I am certainly partly to blame for believeing them. Besides, I knew there were some issues and just figured I'd deal with them. This one is a bit larger then I anticipated, at least for what I paid for it. Live and learn. I'll go ramble on my own thread now.

Update -

I put the rear bench back in, tied up all the loose ends and dropped the 23 in Minnetonka on Monday night. It sounds great at idle and better at WOT ;D Idling around, the tips are about 3/4 under water, so it sounds kinda like an old Cris Craft. Better yet - it didn't sink. Jeff, well done.

However, it's not all butterflies and rainbows...so I took a chance and didn't replace the impeller before taking it to the lake. Sure enough, as soon as I throttled down and ran at low RPM's (under 1,000), it would start to warm up, as it previously had on muffs. I shut it off and tried to figure out if anything else (I hadn't checked) besides the impeller could be causing overheating at low rpm's. I dug into my new t-stat and sure enough, I forgot to tighten up the check balls on the brass t-fitting, which allowed water to simply pass through the t-stat housing and dump into the risers. I'm a moron.

I snugged up the check balls to the t-fitting and the overheating problem is no more! I took it out Tuesday and it ran perfect - nice and cool. I'll post some pics of it all back together later tonight...

Now it just needs to stop raining.... :'(

Bingo - as long as it's dry, I plan on going out Sunday around noon or 1. Hope to see you guys and anyone else that wants to join out there  8)

Craig - I don't know if you have to bottom out on the threads - I just tightened them so there was enough spring tension to hold the check balls snug against the brass t-fitting.

Well we made out to Minnetonka today as you can see I was always in the back.

Photography is not my best subject.

Will be looking for some instruction someday.

Thanks Gregg for the posting of the pics, Kip and Alex also took a few shots

Great seeing everyone! Good day of boating with an early dinner at one of my favorite places to eat when I lived in Mound. Alex and Jeffs boats sound great, Jim has got his OB running like it should and mine ran fine too. As usual I didn't take enough pictures.

HAHA what's funny about the "get your feet off the dash" caption idea is that my buddy Jordan (the guy I'm pointing at) had literally just asked me if it was OK to put his feet up on the dash...right before Jeff professionally captured this candid moment in time.

In reality, my buddy had just earned a giant welt on his forehead by nailing his head on the hatch cover lock in the cuddy. I figured the obvious thing to do would be to hit said welt with my finger. That's what friends are for, right?

Anyway, it was really cool seeing you guys out on the water...Jeff's boat sounds awesome (it's a bit louder than mine), Kip's boat is incredibly clean and Jim's is as nice as ever. I snapped some pics and will post them when I get home from work...
