Re: Evinrude 85 hp trim and tilt

[jeff-register]

I believe the relays flip polarity is all. One for trim up/down & The other is for tilt up/down. You need to locate the correct pair, then reverse the pos/neg polarity. The motors are different too. The first motor is double wound for both directions & the later motor is single would, I believe. I have never been inside this set up but it is the logical way to wire a reversing motor. Later they learned with a DC motor it can be reversed inverting the inputs using direct current.
