I have a mercruiser 470 and the trim is stuck in the up position. the trim pump runs just fine in up and down modes. Has plenty of fluid as well. Suggestions? Thanks in advance.
I had my drive unit stuck all the way down once. I had to jumper out the selenoid with some needle nose pliers and have someone else push the trim/trailer switches while I held the pliers on the contacts. It did work and I was able to get the boat back on the trailer. I got a new selenoid for the up side and it has worked fine ever since.
Well, I got it down, now it just flops around. I can pull it up and down by hand now. Trim motor still runs but it sounds like a motor with no load on it or something. Could there be air in the pump or something?
It only took me a year! haha. It turns out it was low on fluid! Doh! Also had a leaky cyl. Now it will not trim down, only up. Plenty of fluid and I removed any air twice. Suggestions?
