    Using parts of a 1974 85hp on a 1973 115hp

    I have a 1973 johnson 115 with a bad lower unit. I thought I would buy a parts motor to use the lower unit. Correct me if I'm wrong but would any lower unit from a 85-135hp johnson/evinrude from 1973-1979 work? I also don't know if the block is the same size on this motor range. Having a parts...

    1973 115 HP Johnson Clutch Dog Flip/Replacement

    So I took my boat out the other day and when I would approach WOT the boat began to jerk. As my speed would increase the jerking would become more frequent. When I would lay off the throttle the jerking would stop. I did some research and believe this is due to the clutch dog slipping. I was...

    What size helicoil do I buy?

    Recently I purchased a project boat with a 115hp 1973 Johnson on it. As I restored the boat I would periodically start the motor on land. When I went to put it in the water, I couldn't get the engine to run. It would sputter on its own a little then die every time I turned the key. Following...

    When were boat titles first issued?

    I am considering buying a 1974 starcraft but the owner says he doesn't have a title just registration. What type of documentation should I aquire if I buy the boat? Do I need to apply for a lost title at the SOS/DMV? I'm unsure if these laws vary by state but I am located in Michigan.
