Re: 65 Merc Problems

Numbers should be on the front of the swivel bracket or stamped it to the top of the block above the sxhaust plate. Thunderbolt Ign. is CD ign, on the 4cyls. it was battery operated and the 650s 4cyl with CD were built from 1967 to 1971

I've got a similar 65 hp. my serial# is stamped between the two bolts that clamp your motor to your boat.
