Oops I've done it again
« on: June 12, 2018, 11:28:34 PM »
I'm sorry I haven't followed the forum much recently. Since last fall and into this spring I've been helping my buddy Mike with his growing fleet of Chris Craft boats. We have one almost water ready ( '87 Amerosport 250), test splash will be tomorrow. However I realized I haven't done any work on the Gold CVX lately and summer is already here. Seeing that I would like a boat on the water this year and there is so much work to be done on the Gold CVX I kept scanning Craigslist and Marketplace for a suitable quick Glastron project.



So Much Work To Do Yet.......SIGH





Thu Is What I Found....

1986 CVX 18

228/305

Hull and Gelcoat in Great Shape.

Interior Presentable

Boat Is Complete includes center console

Trailer has 2 tires that hold air and all lights are working






Her's What it Needs


Floor is a bit soft in places

Transom has  rot but no spider cracking in gelcoat

side panels in engine bay are soft

a couple cracks in seat upholstery








Oh I almost forgot...

The oil pan has a small hole in it where the connecting rod exited the motor in an unlike manner in which it entered, thus the attractive price.







Here's the plan to get it running this summer

Patch floor where needed

R and R engine --- should be easy as I have 2 305's and a pair of 351's in the garage.  Some people collect Props, I have a collection of spare engines.

While engine is out replace transom wood.

This should get me on the water soon.

After the season I can replace the floor and the stringers if needed, also redo the engine bay side panels.


More pictures when I bring it home.

I missed a price, hopefully it's reasonable.  I would suggest a 350/merc 260 as a replacement, but if you already have a 305 laying around, then why not.  Drop in an engine, prep for water, worry about rot later.

Well Mike I think the price was close to reasonable at 1400.00, as for the engine I have a 305 that's good for 300hp @ 6000 RPM.

Hate to say it, but your alpha is not going to like an engine with a torque peak and rpm that high, but I'm curious to see you results of trying.   BTW, are you kids planning to make the August meet?  We missed you last year.

Mike, the only thing Mercruiser in the boat is the engine. The rest of the drive line is OMC Cobra. When the original motor went bad it seems a PO replaced it with whatever he had.






My plan was to replace the 305 and run with the Cobra outdrive as it looks to be in good shape. The only issue I see is the skeg is missing a small piece. The outdrive itself shows very little corrosion although its been repainted. The gimbal housing, gimbal ring and bellhousing are all in excellent shape with absoloutly no corrosion, the Cobra decals on the trim cylinders are in excellent condition (see picture below). 







Here's the catch.

When I pulled the outdrive I found that the ID tag lists the unit for a 3.0L, which is a 4 cylinder. Wrong gears and a small lower unit.

You're right...the outdrive  is not going to like an engine with a torque peak and rpm that high.


NEW PLAN.....Use the 351 and Mercruiser drive line I was going to use on the Gold boat.

Here's the work I've done so far.

The initial inspection of the engine compartment reveals a small oil leak.







Got home from work 10:00 pm on a Thursday night and couldn't sleep. I had disconnected everything on and around the motor during the past few days so the only thing to do was pull the motor. 25 min. later it was on an engine stand.





Here is the source of the oil leak.

It appears that the connecting rod exited the engine in an unlike manner from which it entered.






I was wondering if the block suffered any internal damage. What I found on the starboard side of the engine makes that question a moot point.





Next up was pull the outdrive than demo the transom.

This is what I found





10 minutes later




Easiest transom demo ever. Except for the top portion I just scooped it out by hand.

Here is the only semi solid piece of the transom.

   



I didn't want to do a full rebuild on the flotation boxes so I just replaced the section with the rot.
Here we are ready for the new wood.





Here is the transom wood laminated and trimmed to fit.










That brings us up to date. I should start 'glassing this weekend.

Good progress, hope you make it on the water soon.  Odd that it came with a four cylinder?  Never saw an 18 without a V8 of some type.

Only engines available for '86 were a 305 or 350. No 4 cyl. Somebody in the past must have swapped the outdrives.  This boat has had some excellent care in the past but some past owner didn't know much about boats as proven by the Mercruiser/OMC motor mashup. Even the radio install is suspect.



Where did he get that vintage radio w/cassette player?


They didn't even finish the work.

I know very little about the OMC outdrive, but it does appear to use the same keyhole as Merc?  I must have been thinking Volvo, which has a different transom altogether.  I wonder if using the outdrive ratios from a four cylinder would work for a while, understanding your engine RPM's will be higher.  Issue would be adding too big a prop to reduce RPM's and thereby causing too much torque on the upper set.  Sounds like you have a solid plan, will you be bringing it to MN in August?

My CVZ-18 had the thru hull exhaust in the same position. I also could scoop out the transom in the upper part because of this.

In 1993 VP and OMC entered into a joint venture with VP supplying the outdrive and OMC supplying everything from the transom forward. When OMC designed the Cobra outdrives they made the keyhole the same as Merc which carried over to VP with the joint venture. In 1998 VP buys OMC sterndrive division and retains the OMC hardware.
Here's the cutout  from my OMC . Same as Merc.







Here's Saturday's work.

Glassed in the temp repair side panels and 'glassed and clamped the wood to transom.
Then it was off to the races. Sprint cars tonight so we'll be busy.

Races ran late last night so I didn't get going today until noon. Yesterday I 'glassed in the transom wood so today I started by adding a layer of 'glass over the top of the transom and tabbing the sides.





While the resin was tacking up I dealt with the rot in the engine mounts. Instead of rebuilding he mounts I opted to use a wood rot repair epoxy. The kit includes a quart of resin, hardener, mixing sticks, mixing cups and a pair of gloves. Everything you need to complete the job. This resin has a thinner viscosity so it soaks into the wood easier. I used about 16 oz. to fill both mounts.I used a syringe to fill the mount through the existing bolt holes.
 I've seen these kits on the market and wondered how well they worked but next time I'll just thin out my own resin or rebuild the mounts.






I had some Black Gelcoat leftover from a previous project so I used it to coat the transom and having enough left I continued down the side panels and to the front and back corners of the engine bay floor above the stringers. The plywood there was mighty soft and some of the fiberglass had broken away so I patched it with woven roving.






Headed to the back of the boat I used the last bit of gelcoat to repair a chip at the bottom of the keyhole and 2 small areas where the gelcoat came off with whatever was used to seal the gimbal housing to the transom. I thickened the gelcoat with cabisil to ease application. I'll come back after it sets and sand it level.

Moving right along. After work it was out to the garage for another round of fun.
Tonight I cut out the keyhole and drilled out the mounting holes. Here I'm lining up the drill fixture in hopes of getting a straight hole. In kindergarten I couldn't color between the lines even with a straight edge guide so this may tax my abilities.






Installed the new drain tube. The flaring tool sits in the keyhole ready for it's next job.







That's it for tonight.

     Curious to know your take on waterproofing the transom penetrations.  The keyhole is easy to get some resin/acetone mix into, but the bolt holes I've had issue with.   I drill mine slightly oversize and use a bore brush from horror freight(disposable) to get the resin/acetone mix in.   I've heard of others coated the bolts with 5200 or equivalent.   Looks like your making good progress, are you bringing it to MN this august?

Well Mike , tonight's work may have answered one of your questions.

I started by drilling the reliefs for the steering arm then bored out the holes for the thru hull. The first hole I drilled was too perpendicular to the transom and the exhaust tip hung up on the moulding on the overhang. A little massaging with the hole saw solved that problem. The second hole I drilled at a slightly steeper angle and that worked fine.

Next I used some more (4oz.) of the gelcoat I had leftover and coated the transom cutout and exhaust holes. For the bolt holes and hole for the speedo tube I used an artist brush to "paint" the gelcoat. We'll see how that works out.






The exhaust tips that came with the boat have an angle cut to them but I prefer to use my muffler tips.
The top of the angle tip extends about a 1/4in. past the transom overhang and the muffler tips are recessed about an inch in.
My thought is to make a 1 inch spacer to bring the end of the tip to the edge of the overhang.
Any thoughts on if I should make a spacer, or just run it with the 1 inch recess?





Sorry for the lousy photos but I'm working alone ( those of you who live in a Glastron free zone know how hard it is to find available help ) and there's not much time between after work and O dark thirty.

Betty and I had a great time at the meet but she felt a little uncomfortable without a boat of our own. Now that seems to be a moot point.
I sure would like to return to TI. When she's in the boat, on the water I'll bring the subject up.

Since it is a wet exhaust I don't see a problem, my CVZ thru-hull are cast aluminum and nearly flush with flappers.  Cosmetically, I could see a preference, but it's summer time now, and time is precious.  I'd opt for leave them, get on the water, then decide over the long winter.

Thanks for the input Mike. You are right, time is short so I'll run the tips as they are. That was easy...as  you have a similar set up on a similar boat.


How 'bout this....Mercruiser Wind Chimes

Got the transom pieces cleaned and painted.

Let The Install Begin!

Looks great, merc wind chimes, that's a new one.  When time critical, make functional, then pretty later.  My tips are nearly flush, your current tips appear to exist to extend quite a bit further, either way, they will work.  Get it done, test for a week or two, then haul it to TI.

Been busy at work and life happens the past few weekends so I haven't got much done on the  Black CVX.
Betty saw it in person for the first time last Saturday and now refers to it as "Our Boat".

I guess that means she likes and approves of it.

Whenever I found time after work I managed to install the gimbal housing, new bellows, and transom plate with the power steering gear.
No pictures of the install but here is the exhaust blockoff plate I had made out of stainless.






Busy this weekend at the tracks. Friday was a 100 lap series race (Dirtcar 358 Modifieds) ad Saturday was a 50 lapper plus the regular features both days.

Saturday I got some cleaning and painting done on the engine.








Sunday I swapped the 2 bbl intake for a 4 bbl., installed a new circulation water pump and new starter along with a new engine coupler.

In wiring the engine I moved the starter solinoid from the exhaust manifold (the original was a log style and the solinoid was bolted to the back of the manifold) to the flywheel housing.

Once that was done I dropped the engine into the boat to check the clearance between the engine cover and risers.

It seems I've done this before...sort of Deja Vu all over again...
 
The only small block Ford offered in a CVX was the 302 and that was with a log style manifold. I'm using center riser manifolds from a mid 90's Volvo Penta so I can use Thru Hull exhaust.

Tha's it for now.

     Those manifolds are plenty tall, its going to be close on the lid.   Looks like fair progress given all the other stuff you have on your plate.   Hope to see it in August.
