1988 Evinrude 110 HP, trim tilt motor problem

[sss5358]

1988 Evinrude 110 HP, trim tilt motor problem <br /><br />While doing my Spring check of my boat and motor, found the trim/tilt cycled very slowly. While<br />cycling the trim/tilt I wiggled the wires down by the motor and the motor cut in and cut out then<br />finally quit. Previously I had cleand all the connections from the battery to the motor and that<br />had helped some. I used an electrical tester and determined that power is getting to the <br />motor on both the up and down wire. I think perhaps the short or (problem) is occuring in the<br />motor itself.<br /><br />Any suggestions on what to do next? The motor housing<br />looks like it is very hard to get off, access is limited. Any suggestions on how to get it off (special<br />tools, tips ect). Any help would be greatly appreciated.<br /><br />Thanks to you both for your responses. I'll use the information you gave this weekend to see <br />what I can do. I found a new tilt motor so I know if I need to replace it altogether I can. <br />I'll let you know how it turned out.

You don't mention your motor or model or trim motor type.. but in your situation, I'd first try getting the motor working manually.. get a battery and some wire, and bypass the switch etc altogether.. see if that works..<br /><br />Second thing, if it doesn't work, pull the motor apart, take a look, its probable that you have very little meat left on your brushes.<br /><br />not a big deal to change either,, but that does sound like your problem..<br /><br />regards<br /><br />Frank

That PTT electric motor is a dual polarity model. Battery cables going to the two wires leading to that motor will run it in one direction, reversing the cables will run it in the opposite direction.<br /><br />Disconnect the electric motor at the connector that leads to the relay box. Using small jumper cables, connect the battery to the electric motor. It doesn't matter in which direction it runs. If it now runs okay, even when you jiggle the motor wires (as you mentioned above), obviously the electric motor is okay and the problem lies elsewhere.<br /><br />However, if the electric motor proves to be faulty, you'll need to remove the PTT assy in order to replace it. To do this, do the following:<br /><br />Have the engine in a tilted position, and make sure that it will not fall. Remove the pin from the top of the center tilt rod. Find the manual release valve at/in the recessed hole that exists near the bottom of the starboard transom bracket. Turn that release valve out two (2) full turns. Force the center tilt rod to its down position. Screw the manual release valve back in. Remove the three (3) retaining bolts on each side that attach the PTT assy. Now, you can remove the PTT assy by tilting the top of it backwards and out of the engine.
