Reworking old wiring

[inaforty]

Macojoe,
I think your 225 Yammie should be pretty much plug and play if you use the correct year factory harness and gauges/sensors, throttle/binnacle. I rigged and 25hp 4 stroker on my Whaler and it was pretty easy but of course a 25 hp is not a 225 either.. Once the pos and neg were attached the harness did the rest. I'm no expert or Yammie mechanic by any mean but that how it went for me. I also put in a Yamaha fuel management system on the Rosborough. Followed instruction and it was fairly easy.

Trying to find out where everything goes and what is need and not is time consuming but what the heck is there to do right now anyways.
