Re: tilt/trim trouble
We had a similar problem with our '91 Evinrude. If your trim control switch is on the Shift/Thottle Contoller at the driver, then it is similar to our setup. We ultimately found out that the wiring inside the control arm fractured and broke - thus causing our trim to lose one of its direction controls.The back and forth motion of this unit (as it is used to shifted or change speed) twists or bends the wires and one eventually fractured and broke over time. Depending on which particular wire goes first, will determine how the the control of your power trim will fail. Even though they try to design it not to fail and route the wires to minimize this type strain fracture (an important thing to note if you decide to replace the harness), it eventually fails - it is sometimes just how long and how much use. <br /><br />Don't know about your control relays but if you can find them (ours were on the power head) you may be able to switch them and see if the problem switches to the other motion. If the problem "moves" to the opposite motion, then a relay may not be your problem.<br /><br />We got a new harness and, in our case, found out there is a connector to plug to connect the new control switch and wire harness vs having to replace it all the way back to the engine.<br /><br />good luck...
