"I have a '98 Mercruiser A
"I have a '98 Mercruiser Alpha I that the tilt/trim (trottle switch operator) that operates the up and down trim does not function properly. The down button works very well however the up button does not. When I hit the up button the tilt goes up very slightly and then dies. The button goes dead. I can hit the down button and tilt will go down back down to full down position. What is causing the up tilt to cut out or limit out after moving and inch or two? The trailer switch will tilt the motor up/down and works perfectly well. Any ideas/help would be a great help.
I was at the barn this weekend to winterize the boat. After spending 2Hrs I think I found the problem. As stated the trim up postion will move the trim shaft up to a maximum of 3.5 inches. If I grabbed one of the two port side limit switch BLK wires and moved them with someone holding down the up bottom on the trottle, it would jerk the trim up another 1/2 inch. Closely looking at the situation I found the top blk limit switch wire on the port transom 1/8" bare. I also think that the connection inside the trim limit switch unit would also not be in good shape. I believe the trim limit switch is a sealed unit. I also have read that to replace the switch is expensive as you need to remove the outdrive. As well they say if you change one switch you might as well change the starboard side one as well. WOW. Here is my thinking. If I were to buy a new limit switch, cut the wires off from the old one, connect them by soldering and cover with a heat shrink electric tube to make it water resistant would this work? Or can I fix the old switch? The bare wire is right up against the plastic housing of the limit switch. My other scare is the often mentioned BE CAREFUL when changing the switch to make sure you do not over extend the 6.5" +- 1/4" travel or you can damage the outdrive severley. Sorry for the long e mail. But these are things I need to work out over the winter layover and fix this spring. Any and all good thoughts are appreciated. Thanks again."
