Hello. I recently inherited a 1982 Invader boat with a 4cyl Mercury Motor. I have no documentation on the boat, no manual for the motor or out drive, and I am new to boating and owning a boat. If anyone would have any idea where I could find a manual for the motor and our drive, that would be awesome. The i/o motor is a 140 HP motor and has a mercruiser out drive. The HIN is MWK40338M82K. If anyone could tell me the model of the boat to that would help greatly help! Thanks a ton!!!
