  • Mariner 20e 6A9 Wiring Help

    Hi there,

    Can anybody please help with a wiring diagram/or just guidance for an old Mariner 20e 20hp 2 Stroke? Itís a 6A9 model I think something like 1982? Not 100% sure of the year. I believe these motors were actually built by Yamaha.

    It didnít have the controls etc when it was bought, so there is just a plug (7 pin).

    I am am hoping to connect up the electric starter motor & a kill switch if possible, both of which Iíll need to buy. I guess Iíd need to cut the plug off and figure out which wire is which! Not sure what else runs through the plug?!

    Any advice greatly appreciated!!

    You can order Yamaha 704-82570-12-00 key switch with kill switch and warning buzzer and a Yamaha 688-82586-50-00 7 pin main harness. It will plug right into your motor and will be all you need.

      Great thanks. Iíve been looking and is it correct that the main harness has a 7 pin plug on the motor end, and then an 8 pin plug to match the switch unit on the other end?

      Also the only retailers that I can find are all US based, are you aware of any UK sellers that might stock the main harness?

      thanks again for the reply.

        Yes 7 pin engine and 8 pin key switch. No I don't of any place in UK but I would think any Yamaha outboard dealer would be able to get it.
