Im thinking of purchasing a 21.5' Fiberform fishing boat that has a 1994 mercury 5.7L V-8 with a 280 volvo outdrive. Was wondering if the merc/volvo motor to drive relationship will cause problems with compatibility for replacement parts and such. Off the top I can think of water pump systems being different between the two, anything else I should be looking for, going for a test run this weekend, want to be sure im not getting myself into a disaster.
