Hi I have a 6hp Johnson Seahorse model CD 22M Serial No C451593 I know the year is 1965, does anyone have any information about it, for example fuel ratio, plug gaps or where I can get hold of an owners manual. Any information will be much appreciated.

Howdy, Mike.

Welcome to iboats.

Your fuel mix is 50:1, TC-W3 outboard oil and 87 unleaded regular.
Plugs are Champion J4C, gapped at .030"
Set points in the mags at .020"

You can get a reprint Owner's Manual at kencook.com or might get lucky on eBay for a lot less.

Thanks JB you old sea dog but I thought my engine couldn't use unleaded because of its age?

Lead is only necessary to lubricate unhardened valve guides (and to boost octane). No valves, no need for lead.

In other words 2 strokes never needed leaded gas
