Re: 1956 15hp evinrude help
The 56 is not factory engineered for an electric starter. Guess you could try to jerry-rig one using enough parts from a donor 57 but that would be pretty dicey. If it's got fresh ignition parts, ie. good coils, points, condensors, plugs and wires, it should pull start on the 2nd to 4th pull. Once warmed up, they will go with one pull. A whale tale may help with planing if the transom allows the lower unit to ride too far below the stern. The cavitation plate on the LU should be even with, or within an inch (higher or lower), of the bottom of the boat if the motor is rigged correctly. Too deep and it will plow, too high and it will cavitate and act squirrely. You can use spacers to get the right height or a jack plate, if you're into fabricating your own stuff. With the 15 hp you may have to rig an extra pilot's seat, so you can sit a little forward of the rear seat...this will help get the weight distribution right and help with planing, performance too.
