For the life of me I can't figure out what year the motor I have is. I found the SN located on the transom mount. The number is 5016277. When I look it up in various sites nothing comes back. Should I assume it's a '77' based on the last two digits?
Physically, it's a black cowling with Mercury 75 in blue on the side. The motor is the black 'comet' twin cylinder 2 stroke motor with the thunderbolt ignition (I believe). I say believe because I think I saw that on the cowling by the pull-starter. The spark coils are orange.
Ultimately I'm trying to troubleshoot a single cylinder running problem, but would like to know the year in case I have to buy parts. I won't go into that here as that's another thread in it's own right!
Thanks all!
