How do you tell what year, talked to two dealers, they said did not have enough numbers. I went to look at boat again this morning to recheck serial number, owner said I could not get close to boat until, the fish and game people had removed a gator.

Anyone have a manual for this engine, that will share some specs. I need stator output to pack, pack output to coil, and ohms for coil.
