Bravo trim drops
 

I am having an issue with my 93' Mariah Z2350 Bravo outdrive dropping in 3 to 4 hrs. I pull the boat out of the water and in 4 hrs the outdrive is touching the ground, obviously both trim rams are bleeding off, are there any specific tests to isolate the trim solenoid or the rams?

Mine did same thing it was the check valve in trim pump.

Thanks, I will check it out

I had an internal oring on the ram fail and cause the same problem, would hold trim while driving either, it was just one ram and very low hrs. Everyone had me chasing check valve in the pump and that wasn't the problem. The check valve can cause it, but the ram can too. No external leaks on mine
