Has anyone had experience converting a non electric start to an electric start 1985 Evinrude 25hp. I have acquired a parts motor that has everything I need, I can easily transfer all of the components from it to mine, but im not sure if I have to worry about timing and maybe other things im not sure about that might damage my existing motor.. any tricks to removing the flywheel without the proper tool? trying to do this on a budget without having to bring it to a mechanic $
