Need some help, but first a little history.<br />Replaced the tilt/trim pump on a 81 Wellcraft V20 140HP mercruiser. New button/wiring harness with the pump too.<br /><br />The day I put it in, I filled the resevoir till fluid came out the vent hole. The pump seemed to work fine, the outdrive would go up and down without a problem. Only worked it up and down a few times. Add some more fluid after.<br /><br />Then I noticed it started moving slower and slower. The last time I lower it, it lowered very slow. Now it won't go up.<br /><br />I disconnected the rams from the lower unit and I am able to raise and lower the drive easily. With the rams disconnected I tried to raise them, but they did not extend. When I lowered them I noticed one ram did move in a little. The motor sounds like it is working and trying to move it, but it just doesnt move.<br /><br />Any ideas? I would love to get this boat in the water this year.
