Wiring for keyswitch on 1978 55HP Johnson

[vaughneric2000]

The control box on my 1978 55HP Johnson outboard was submerged in satwater during a hurricane last year. The motor survived, but the keyswitch in the remote control box was ruined by the saltwater. So, I bought an exact OEM keyswitch replacement. The old switch connections were corroded and eaten away to the point where I couldn't tell where any of the connections had to go on the new keyswitch.<br /><br />The new keyswitch connections has the following letters:<br /><br /><br />S<br />I<br />B<br />M<br />M (a different M than the one above)<br />C<br /><br /><br />Could someone tell me which wire goes where on the keyswitch?<br /><br />Thanks a million,<br />Vaughneric2000

Hey Vaughn...welcome to iboats. Let's see if we can help.<br /><br />S - Start - will either be the white or yellow wire which ever you have.<br /><br />I - Ignition - Will be purple.<br /><br />B - Battery - Should be the red wire.<br /><br />M - Magneto in the old days but now ground - Will be the black/white stripe wire (I'm going from memory here) <br /><br />M - Same as above - Plain black wires.<br /><br />C - Choke - purple/white stripe.<br /><br />If you have any thing different, hollar.
