Thanks Bigshrimpin,
Here's what the owner wrote me:
"The engine was rebuilt by Ron's Marine in Yucaipa in June of 1998. I bought it blown up, it was worse then I thought..... The complete rotating assembly was replaced. One of the power packs went out 3 years ago when I was in Lake Havasu so I had Barnicle Bills replace both of them ($800.00). It is oil injected and has been run on Mercury Quicksilver oil ONLY! The engine is a 1988, I believe 2.0L. There is nothing wrong with it, it starts, idles, and runs perfect. I am having Jack at Marine Performance Design install a Jet and heavily built 460 Ford in the boat. That's the only reason I'm selling it. Here's a link to a youtube video of the engine running on my boat.

If you need a 25" shaft I have an equally nice 235 Johnson I'd sell for $1000.00. The boat is in an enclosed storage unit so pictures are a bit of a hassle, but it looks like every other V6 Mercury, no cracks on the cowl or anything."
Any more thoughts on this. Or what else I should ask him? -McGill
