Need info on Model FD-20C

[zdurst]

Hey Guys,

I just bought a Johnson Seahorse FD-20C.

Can anyone give me some info on this motor. I think that its a 1966 20HP. Any other info would be great like fuel mixture, spark plug gap, what oil to use...

Thanks a lot.

Zac

Welcome to iboats.

Your year is correct, so mix 50:1 regular 87 octane fuel to TCW3 oil

Use Champion J4C plugs gapped to .030
