Having problems with my Mercruiser trim, it trailers fine, goes up and down when underway moving slow fine but once on plane it will not trim up. Any advice out there thanks in advance.
Which Mercruiser trim do you have? Mercruiser has had many different systems over the years.
92 Alpha I Gen II explains it all.
Did this start all at once? Any work done on the pump trim lines disconnected at some point.
Sounds like you have low pressure from the pump. The pump does have a high and a low pressure side, and wondering if things got crossed up somehow.
If nothing is crossed, you probably have some problems with the valves in the pump itself.
