Re: Trim not working, motor stuck in down position
I had the exact same problem last week on my OMC cobra. Find the pump located aginst the transom (inside the boat). From it should be 3 wires - mine are blue, green and black. Disconnect them from the harness so there should still be about a foot or so of cable to the pump. Using jumper cables, directly connect the black to - on your battery and the blue to the +. This should lift it, if goes down then connect the green instead of the blue to the +. This is also a way of checking that the pump is not the problem. This saved me, I was able to trailer on home.
Good luck.
