    Default Convert to electric start

    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.

    The starters for that motor--there are two types--are hard to find used, and one of them is very expensive.


    Can you post a photo showing where the starter goes? From it we can determine which type you need.

    A lot depends on where you live , used ones can be found where these 20's were popular.------------------It is not impossible to fabricate a bracket to adapt any other small starter.-------Not a big deal if you do some looking and research.

    Agreed if you have the tools and technique (like me: I even build my own props).

    Just my luck ! Would you happen to know the part number of the starter that fits this motor serial # 3758427? There was on on ebay yesterday that the auction ended this morning for $35 that looked rough and there is one on there tonight for $225 with a part # of 50-47216 . It has a "loose lug" . These starters looked different from each other , I'd just like an idea of what I am looking for. As far as making a bracket, I think I could do that, or get enough help from friends I have in machine shops to make it work. If I could just get enough information as to what other starter that might work maybe I could get the ball rolling. Thanks for all the help so far.

    There were two model numbers back in 1974 for a mercury 20 hp and they were 1200204 & 1200224. When you look at the parts list it shows the parts catalog part number to be 90-65145 MERC 200 PARTS LIST.

    Here's the list for the electric components for your engine, The starter part number is in there.

    And here is all the parts for your serial number range.
    http://www.mercruiserparts.com/selec...?doc_nbr=65145

    Your starter part # would be 50-47216.

    I notice a few 'minor' items are missing: The starter and flywheel, for starters (punn intended).

    Thanks Jeff, It appears like Graham may have some of the missing items covered in the link below.
    http://www.marineengine.com/boat-for...rcury-outboard

    Merc may have anticipated the flywheel already geared for a starter in the service bulletin But you never know, it was the 70'sJ/K.

    Also tsigmon, at some point 50-47216 had Superseded to 50-97949A1
    50-97949A1 (NLA) STARTER ASSY
    50-47216 STARTER MOTOR
