Age of a Johnson

[Colin K]

Hello,
Bought a 15hp Johnson at the weekend !! Good price but a bit of prettying up to do also one of the cast cups that hold the rubber steering damper is broken so Ill need to find one, I have an old 6 & 8 hp rude so wonder if its the same ?
Does anyone know how to work out the age of the unit from the serial / model number. I think its q old as its a sea horse eeeek.

Thanks, Col

Hi Chaps,
Thanks for the info and the educational video !! Looks like I have a 74 model. Just after I posted my question I stripped it right down and apart from a few purely straight mechanical problems (twist grip is had it and a damper casting broke ) It seems ok carb is clean and a massive spark. Put my finger over the plug hole and turned it over and it felt pretty good compression !! Do you just test this properly with a standard comp tester ? and if so any idea on what its meant to be ?
Ah and the video reminds me must get a new bulb for the fuel line !!! ha ha.
Thanks Col

A Suzuki seems, well, inadequate after that
