I have a 55hp Johnson Enforcer with the dura-jet lower unit. Everyone tells me it is the same as a regular Johnson 55hp--it does not seem to be. I would like to put an electric starter on the unit, but the bolt holes do not seem to match any Johnson starter. I have been told that this has been done; however, I cannot locate anyone that has done it. I cannot find any literature/manual on the motor. If someone out there could help me I would welcome the response. Thanks!
