Default Bravo one powertrim acting strange

Powetrim started acting strange this year. First symptom while underway with drive trimed up, if i trim down, will often go down quickly with a slight bang. Second symptom, while underway if i pull quickly the trottle to slow down and then push back on the throttle to rev up there will be a bang... I guess they are related... Any hints on what to look at? Thanks

What is "trimmed up"?
How far many digits above neutral are you trimming?

Feels like the drive becomes loose underway. Acting like a small outboard ajusted to tilt mode when you back up and the prop comes up. Does a bravo act the same to protect from hitting underwater objects? If so, mine does it to much. Never felt that before

whats hapenning if you trim up full tilt for the week and see if it goes down by itself on trailer?
if it does, look for visual leak, if no leak, trim ram or pump lets the pressure go down
