Need help with 88 supra comp

[drew10483]

Was given a 1998 Supra Comp with no engine. Having to do a lot of restoration work on the boat itself. Bought a 351 Windsor to put in it. Need to know where I can get any mechanics manuals so I can properly put the motor in it. Any help, or comments are greatly appreciated! I will try to post some pics of it in the next few days.

So the engine (351 Windsor) came in. The coupler that was on the engine is to big to connect to the transmission. Where can I get the right part for this and what would it be called? Here are a couple of pictures of it. It is 26 splines.

check out www.skidim.com. they are very helpful, vince owns a comp if i recall correctly.

you're looking for a damper plate.

You mean 1988 right? That boat is definitely 1991 or older.

what windsor motor did you buy? as for a car/truck motor will not work.

[drew10483]

yeah that was a typo, it is a 1988 model. The engine is a Mercruiser Marine Engine Ford 351 Windsor Welcraft. I need lots of help =)

You might consider trading the Mercruiser for a Pleasure Craft Marine (PCM) 351. I suspect it would take far less scrounging to make it mount and mate.

how hard is it to do the wetsand? i have spent a few hours with polishing compound and a buffer. boat looks considerably better but not to my standards.

i don't know much about the engines...where would i be able to locate a pcm and what are the pros and cons vs. my engine...trying to make this is as easy as possible for me so i am up for anything =)

[jsandy]

the PCM 351 came in the supra so the rest of the boat is made for the PCM motor. the wetsand part is not hard it is just time consuming. Start with 1000 grit sandpaper. Sand all of the boat that you want to buff, use a foam pade about 3in by 5in foam pad that you wrap the sandpaper around, then go over everything again with the 2000 grit then buff with a buffing compound then finish with a polishing compound. again this is a long process

I'd start with 500 or 600 grit. It will be a lot of work either way, might as well try to cut through the bad stuff as quickly as possible.

I have a the complete drive train out of a 1988 Supra Pirata. Ran good and has 1040 hours on it. PM me if you are interested. It was just pulled out of the boat. [email protected]

Of course the PCM 351 is the original equipment for your boat. Having a PCM would simplify the installation. I don't know how to source one, other than perhaps star hunting craiglists. you might even post a wanted ad. The internet is full of shops that do overhauls of PCM engines. Some marina's and boat dealers may have PCM take-offs availible for sale.

Better yet, buy Century63's.
