Re: Johnson Starter

[Mumbles]

I’ll go out on a limb here and say a 12 volt starter, bracket, and matching flywheel from an 18, 20, or 25 horse motor thru the mid seventies should be a plug and play installation on your ’57 motor. When I compare late brackets to early ones, the mounting holes sure look the same. The only difference I can see is where the solenoid mounts. 57’s had an electrical box inside the boat while later motors had the solenoid under the hood, either on the starter bracket itself or on the port side bracket. I will admit I have swapped flywheels around but have never tried fitting a later starter bracket to an early motor.
