The outside of my trim tilt motor has just corroded away. Currently still working but know its only a matter of time before a new one is needed. Been out searching for just the motor or even the whole setup so I can take care of it over the winter. The question is always... Is it a 2 wire or 3 wire ? Does anyone know of the 84 has a 2 wire or three wire ? Or can anyone tell me how to check to see if its a 2 or 3 ?
