    Default Mercury 20 HP starter/flywheel install


    I'm wanting to change my 1978 manual start Mercury 20 HP over to electric starter was wondering if anyone with a similar Mercury 20 HP electric start could send pictures of how starter is mounted on engine most pictures I've found don't show much. To much arthritis in shoulders to pull start anymore.

    This kit should have everything you need to convert it to electric start and charge the battery. The block should already have the holes to mount the starter and its lower support bracket. (make sure you run a tap through them to ensure you have clean threads for the new bolts)
    Just a moment...

    Good luck!

    Agree but……

    Even at that price it bets yanking a pull rope if one’s shoulders are arthritic. Hope you can get one and get it converted over.

    I did a 9.9 quite a while back and it was easy. Those starters on those small motors don't draw a lot of current so if you have a way of charging the battery once in a while you don't need the charge coil and the rectifier. It worked for me.

    Yes Marine engines didn't have one.

    if someone with this motor with electric start could send picture of starter and how it mounts I'm sure I could find starter that I could make work

    I know a guy that works on small outboard engines that He starts them with a cordless Milwaukee 1/2" impact on the main nut over the flywheel.
