Ball park how much does a pair of 350 hour Mercruiser 575 SCi go for? Assume good condition.
Thanks.

complete drop ins or long blocks ?

Seems like at 350 hr they likely need a complete rebuild. My suggestion is to get a quote from MRE Power Products. Mike Riley did/does much of the work for Keith Eickert....and me. If you wanted, getting to 650-700 HP should be pretty easy. As is, they aren't worth much.

Complete drop ins. May have been refreshed. Need ball park value>

What year? Even if they are stock you are talking blower rebuilds and head gaskets for sure, and while the heads are off valve springs would be a good idea. If they are salt motors the intakes rot out. More info would be helpful.

I would say "it depends". Heads rebuilt and blowers checked yes. But not complete rebuilds - if they've been taken care of.

One of the reasons I asked what year was because early 575s had cylinder wash down at idle on the rear 4 cylinders. Later models with dual IAC did not have that much of a problem. Either way a custom ecm tune is the way to go.

10 grand each / They need rebuild. maybe you could run them they way they are but check the compression

X2. And they are already out of the boat. map them before you put them in anything

You buy in the crashed patriot?
