You definitely need to check for rotten wood. That era of boat was built using a lot of fiberglass over wood. If there's any soft spot in the floor there could be problems. Fuel tank- clean it out and check it for leaks!!, If there's no rot or tank leaks then work on the motor, but remember the you should not run ethanol fuel in it. New fuel will ruin the old rubber lines and gaskets, plus other problems. Oh, and make sure the fuel tank is not fiberglass, the new fuel eat up fiberglass. Been a big problem around here. Not trying to dampen your spirits, just been around boats my whole life... But when working, they're a lot of fun!
