Seeking info on 3.0 engine replacement, I have a 3.0 Mercrusier engine that is blown and would like to replace it with a 3.0 Cobra engine. The Corba has a Omc outdrive / Mercrusier outdrive for the Mercrusier engine. I purchased the extra boat for the parts and the Cobra engine appears to be the same model as the Mercrusier-not sure about the flywheel and other outboard attachments. Can this Cobra be mated to Mercrusier outdrive without any problems or would it require to many changes to fool with.........Thks

pick up any other 3.0 liter, strip it down to just the long block, then build it up with your parts from your busted 3.0. Mercury, OMC, and Volvo all bought the 3.0 from GM. just make sure your about the same vintage, 1990 and older, or 1991 and newer.
