Bought an old Sea Horse outboard, Model # TD 20, Serial # 669862. Don't know the HP or year, and need a coil. Thanks. ...Found out it's a 1946-49 5.0hp, but still need a coil. Thanks.
Howdy, Taz.<br /><br />Your Johnny is a 1946 to 1949 5.0hp. One of those rare cases where they used the same model number for several years. I don't have the serial number data, but that can tell you the exact year.<br /><br />Use Champion J6J or equivalent, gapped at .030.<br /><br />Gap points at .020 and burn 24:1 fuel mix.<br /><br />Good luck.
