Re: [OMC-Boats] oil leak....

ahhhh - it's an even fire 252 V6 manifold - ok. Thanks for digging
that up. Nevermind the carb fit issue, but it shouldn't affect
anything else with the engine performace to have an even fire manifold
on an odd fire engine should it? The water and air are still going
to flow around in there regardless of which piston is firing in what
order right?

So my bigger question is did the even fire's end up in any OMC
boats? Was it just for cars? What i'm getting at is if there was
a marine version of the even fire, then maybe there's a marine
version Rochester carb out there for it that will fit the bigger bolt
pattern and allow me to get rid of all those stupid adapter plates and
gaskets i have to have to make the odd fire RC2 carb fit. Unless it
was getting me some big performance boost (which it's not) I hate
having that jury rigged home made crap on my engine. Even though it
worked. But I LIKE having that extra water temp port on this even
fire manifold, i'm using that port, and I don't want to necessarily
go back to the "correct" manifold and lose that port. So If flying
fish for example had a 252 V6 RC2 carb maybe i'd be set with the best
of both worlds.

I have my existing carb all boxed up ready to send back for a re-
build, but now that I know what I have and can talk to them further
about it all - thanks!!
