I have a 1974 20 hp Mercury manual start that I would like to put an electric start on. The flywheel is already geared so I guess that is a plus. I have tried to search the forums for previous threads but no luck. If this has been discussed before just point me in the right direction. I have talked to several different shops and no one is really interested in doing the work so I guess I am let to do it my self. My local shop said if I can find all of the parts they would be glad to help but finding the parts will be a problem.
