Are you replacing the Outdrive as well as the engine? I got a quote for $6,600.00 for a brand new total replacement. But I opted for a new outdrive unit , used , my engine runs great. The volvo is a great engine, pricy though, pricer yest when they break, goldplated parts. Try looking in the boat trader , I think there are deal on long blocks and complete motors, Mercruiser.
Good luck,

Hi there! What model of motor do you have now? I had inline six mercs in mid 70 20's. One I changed to a v6 volvo and the other I replaced block with same inline 6 but added fresh water cooling. Had to rebuild engine compartment for easier maintenance on volvo and personally I felt that the early mercs were easy and less expensive on maintenance. It really depends on what you are into.... I also found both was okay on fuel with trim tabs.

When I bought the boat a few years ago it was refit with a new 4 cyl volvo. Had no problems with the drive, tons of trouble with the engine (pumps, starters, drive cones, rust, flappers,carb trouble, exhaust manifold crack....) Went through 2 blocks in three years. Now I look to replace the whole thing with the Merc 4 cyl, with freshwater cooling. Did these rigs origianlly come with 6 cyls?

Nope, Only the 4cyls. I think that if My engine blew up i would put the 4.3 Litre 6cylinder in her.
