I second Scotts offer, I would enjoy the chance to look at another OMC boat and compare notes...one of these days I think it would be cool to do a "cruise in" out on the Willamette


Glad you found your oil leak, I was concerned that you might have damaged one of your gaskets looking for that rattling noise...


Your research confirmed my suspision, your manifold is for an EVEN fire buick V6. The 225 ODD Fire is basically a V8 with 2 cylinders lopped off as Buick decided to make something a little smoother idling they changed the crank, cam and firing order, recycled pistons from their current v8 production in 1973 an voila 231 even fire,
 http://en.wikipedia.org/wiki/Buick_V6_engine
which settles another cuiosity I've had for a long time, an even fire manifold DOES work on the 225, which makes me think the inverse might be true......interesting.....You'r manifold will also go on the 252 evenfire.

Looks like you are getting this all settled out...glad to hear it.

Cheers,
B.C.

Hey Jeff,

Let me know if you need an extra set of eyeballs to look things over..I've always found that someone to do a quick look over can find something simple that I miss on my own..
