Im just got a 15' something with no engine or controls. A guy is selling me a 1987 35hp Force with controls for $600. He says the motor is in very good shape and he's selling because he's upgrading to a 40 hp with tilt & trim. This is the first time I've ever dealt with anything about boats so I'm very unsure of dropping the money for it without knowing what to look for. Any help would be greatly appreciated, Thanks!!
