Re: 66 40hp johnson seahorse elec. shift

Sure, it can be converted. You need a long drive shaft, a 5 inch extension housing, the spacer tube and o-rings that go above the extension housing, 5 inch extensions for the two water tubes, or 5 inch longer tubes (note the spray hole in one of them), along with the longer big bolt and extra set of small bolts. The electric cable works in both long and short, so the one you have is OK. But you need a 5 inch longer insulating sleeve that goes over it to protect it from exhaust heat. The shell sections covering the extension will make it look nicer but aren't absolutely necessary.
