I bought a boat with the above equipment. Boat and outdrive are '95ish and engine is '06ish. My question is what maintenance should and can i do? I changed oil and filters and outdrive oil. Bellows look good so i am going to give them till next fall. Previous owner said gimbal was changed when motor was replaced. Is there anything else i should do this season? I didn't see anything greasable on the outdrive. Can i grease the gimbal our universal joint without removing the drive?
