I have a Omc model 990240G serial W567620 1977 year 351 Ford. Can I pair that up with a Mercruiser or Volvo Intermiediate and outdrive?

Re: Question

You will have to remove all the old OMC except the long block of the engine, and install Merc parts in place of it. After you rebuild the trandom to make it thicker and plug the huge stringer hole, and possibly rebuild the stringers. Would be a lot cheaper to find a boat with the power you want.

Appreciate the answers from u and Bondo. Thats where I was going with the question, was finding a donor boat with blown 351 a viable option. I can do the transom and from previous experiences appreciate the time it will take. Fortunately I work cheap.

I have all the where with all to throw the 351, the OMC housing and outdrive back in, but understand its reputation. At the least I think I'd keep a back up housing and outdrive around.

Why am I hepped up on this boat? Its a 23 foot with a flying bridge that tows like there's nothing behind my truck and perfect for the big mountain lakes up here. Very moveable and all the comforts inside.

So I'm just tossing all these ideas around looking for my best solution.

Re: Question

I did not want to put anything with OMC on it back in my boat. After doing a lot of looking around I've found a sbc mercruiser set up with a 888 outdrive.
Its also a Campion like mine approx same age so if I need to modify my stringers I have that one to pattern my renovations after.
Question.
1) Will newer Alpha outdrives bolt up to the intermediate housing presently hooked to the 888?

I didn't see this 888 outdrive hooked up to the sbc engine and pushing a boat around. I've been reading mercruiser outdrives have different gear ratios for different engines. Do the 888 outdrives have different gear ratio's?

Ayuh,... The 888 is an old MC-1 drive that was married to a SBFord...
But,...
Atleast it's the 1.50:1 gear ratio for a V8...
