Project Carla: 74' CV-16SS Restoration
« on: April 17, 2020, 07:29:30 PM »
Hi All,

I was finally able to gather all the pictures I have taken on this project up until now. Here is a link to the album: https://photos.app.goo.gl/cPjG8hFVWJQfEm9WA
There is approx. 750 photos in there currently, some videos too.

For the power plant I decided to keep it period correct so I found 70's 888 parts boat (my dad has decided to restore that one, it was a slickcraft SS204). The guy I bought the parts boat from also happened to have a freshly rebuilt 302 (I'm a Ford guy anyway) that he threw in on the deal. So basically I got a whole 888 drive system with an extra rebuilt engine for $600.
It wasn't so easy though, this winter I wanted to get the spare engine all setup and run so I spent some time doing that and finding many disappointing things. Whoever rebuilt it must have just slapped it together because it was missing the oil pump driveshaft, the exhaust riser gaskets and block off plates, the fuel pump was bad, and they installed the thrust bearing in the wrong spot.
Anyways I fixed all those problems and re-torqued everything, broke it in, and it runs pretty great now.

As of right now the engine is in and resting on it's new mounts, I wanted to mach up the engine in there to make sure my new engine mounts were correct. I used 7 laminated layers of 3/4" plywood for the mounts.

The deck is installed and the foam has been poured underneath.

As of this week I replace  the dash cross support, the original was broken in two

Today I glued in the port side stiffener, a piece of 1/2" plywood. The original one was about 60% rotted, but the remaining 40% was a pain to remove... I was concerned the new plywood pieces wouldn't form to the curve very well, but they did just fine.

Anyways, I'm excited to share the rest of the journey!

Looks pretty good. I am also in the process of rebuilding a cv-16. Mine is a factory V8 boat.  What are your plans for and engine cover?
I think this has become an addiction.

Thanks! As far as the engine cover is concerned I plan to reattach the original flanges to the hull that the original opening had, then try to make a mold of a cover similar to what the original V8 cv-16s had. I've seen your restoration so far, looks good too! Is the link to the other photos working? First time using google photos.

Pulled the engine back out today. Hoping to get to work on the construction of the area where the trim pump and battery go. Does anyone have any pictures of what it looks like in the stern on both sides of the engine? I know portions of each side have foam in them, but I'm not quite sure how they should be constructed since they were already removed before I got the boat...

Before I pulled the engine back out I messed around with coupler alignment just to see what it was like and get a rough idea what I was in for on final assembly, I've got a lot of experience with a 4 cyl, but the v8 setup was new to me. After a half an hour or so I got it to go in with one finger so that was a good feeling. Interestingly enough the adjustment bolts fit a 33mm socket perfectly.

Besides that it was a beautiful day here, just a bit of wind but sunny and almost 60!

sides were filled solid to the panels you see. battery sat in front of the motor, you can see the orig tray in the pix. the orig CV16V8 was only offered in a volvo so there was no trim pump.
i am loosing the foam and making storage there, i hope to find room in front of the motor on the starboard side for the trim pump.
another odd thing, ours did not have a blower in it either.

Awesome! Thanks for the details guys!

I think I will be doing the same, making storage on either side. Ah yes, the volvo trim system was electric I think? I'm going try to fit the battery and trim pump up under there too, if it doesn't fit I'll probably end up doing the same. Seems like not having a blower would be against some sort of CG regulation? Then again I'm sure regulations weren't as strict back then. I also found it interesting that they just embedded the vent tubing and everything else in foam...

Got some new goodies today!

A bunch more fiberglass materials, resin, 1708, mixing cups etc..but also some more interesting purchases.

I was tired of those cheap plastic pitots you normally get with a speedometer kit. I found this really nice adjustable stainless steel one for a pretty good price that includes a mounting bracket. They also sell a hinged bracket as well, which I will probably end up getting too.

I also ordered a refurbished Holley 4160 from ebasicpower. I found the correct 4V intake, PCV spacer, and throttle cable bracket on ebay. My flame arrestor was pretty rough looking so I found a new one of those too, only $32 and its a Barbron brand one just like the original from the mercruiser factory. They had several heights, but I bought the 3" tall one.

As far as work on the the boat, I have glued in some resin coated wood backing pieces around the perimeter of  the engine opening, this will be so I can reattach the factory engine cover flanges to make it look pseudo-factory-esque. With a bit of glass work and fairing anyway haha

Sadly we got a bit of snow here today too...

Made some more progress yesterday on reattaching the factory engine cover flanges. Glued and clamped with PL, once the glue is set up I will glass from underneath, add some glass on top, and then fair it to shape:) It's funny how they designed the cap, especially in the stern area, not one surface is square, everything is at some slight angle or curve, but I suppose that's what gives it the styling.

Yeah, just need a bit more clearance in there:)

Glued on the port side flange today, added some peanut butter filleting underneath the starboard side tonight, then I'll put a layer of 1708 over it, repeat on the port side and then focus on the top, that's where the real work begins...

Also took a second to scrape away some of the extra sun crunchified artificial burl wood decals on the sides, I think I see a peek at the original finish under there haha

In other news, my starboard side exhaust manifold looks to have been repaired at one point because out of the corner of my eye I spotted something that didn't look right, got a closer look and yep, jb weld. Since the other side had already been replaced with a much higher quality (and heavier...) osco manifold, I decided to find the matching starboard side one, osco #5603 and just by luck I scored one on ebay, brand new!

Had some down time today so I decided to finally pin down the wiring diagram for the whole boat. It's a combination of the Mercruiser 888 Service manual diagram (the later model one that includes the circuit breaker and oil pressure switch), CV16SS wiring, and some extras.
I figured I'd post it here in case it could help anyone out:)
I can also supply a PDF version if needed.

Might consider adding a safety switch(interlock) to that schematic to interrupt coil power.
