Mercrusier trim pump leaking down

[stanton]

My mercrusier trim looses pressure. Theres no external leaks so I'm not loosing fluid. I'm assuming there's a bad seal but not sure where to start. It has the pump on top with the plastic reservoir on bottom. Any help greatly appreciated.

had that issue ,would bleed down in a couple hours took the pump apart,found a small piece of metal stuck under a check ball, removed it, cleaned internal parts & flushed the lines & has been all good since.

Mine bleeds downs pretty fast, need to bump the trim every few seconds to keep my bow up. I'll pull the pump to check the screens.... Hopefully that will fix it.
