    Can I replace my 1994 Mercruiser 5.0 2BBL (305) with a 1998 5.7 2BBL (350) ?

    Hello everyone! I bought a 1994 Bayliner 2452 with a carb’d 5.0 mercruiser a few months ago and just used it for the first time a couple of days ago. The boat sat for about 3 years before I bought it but it fired up and ran pretty good. On my first day I replaced the leg oil and fuel water...
