LT-1 compression?

I will be looking at a '95 Prostar w/LT-1 engine (400 hours). What kind of psi, should I see, when I do a compression test? Are there any unique items to look at, with this particular engine?
Thanks

Manual lists compression ratio at 10.5:1 with compression pressure at 200--225 psi. Max. allowable compression variation "highest to lowest within 75%."

etduc, where's the boat located? Got any pictures?

/don't worry, I'm not trying to buy it out from under you.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

Alexandria,LA. However, probably won't be looking at it, was on ebay a few weeks ago. Not bad, kinda middle road. I just have a thing for the LT-1 engine.

Man, wish I jumped on yours. Timing is everything, oh well.

Got other irons, in the fire.

Anybody, want a heck of a deal, on a 1990 TRISTAR?

Yeah, Alexandria is a bit of a drive, but not all that far. Mine would've been closer, but no LT-1. Here's a 93 205 for sale at a CC dealership in Houston. Doesn't specify engine, but I'd bet it's the 351.



Is it me, or does that fly high pole have coconuts on it?

I'd be more concerned about too much variation between cylinders.

Neat boat dealer, u can test drive boats, on site. Nothing wrong with 351w. My TRISTAR has 2000+ hours, and runs strong. I'm looking for a newer style open bow hull. (Wife won't go for a 190.)

Since the 197 is way out of the price range. My default is a pre 96 205, unless someone's got a sweat heart deal and wants a 1990 TRISTAR, here in TX.

Yeah, I've never been to that dealership, but I think they run M3 Sports (same location). One of the sales guys is on the PN forum quite a bit. Derrick something-or-another. Anyway, it has under 500 hours on it.
