Same thing happened yesterday to me but both drives. Trim pumps working but neither drive will go back down. Finally had someone stand and jump up and down on the drives and they lowered. Anyone got any ideas on the problem? What is the possibility that all rams would cause problems at the same time? Boat sets on hoist in salt water.

check fluid level in pumps.

Both full. It is acting like rams are locking on something. Very frustrating.

sometimes if the boats been setting for a while this wiil happen usually after winter.run the drive all the way up and after its up stay on the switch for about 5 or so seconds then run the down button doing the same thing.then back up again staying on the button for about 5 seconds or so.if after 5 or 6 times and it doesnt start going down theres a good chance that the o-rings in the rams have stuck against the outer cylinder and it will need to be disassembled.always make sure the resovoir is full

the down side is MUCH weaker than up. up has to lift drive against all your power when trimming. all down has to do is stop holding it up, and the prop will push it down. designed that way. if doesn't go down good, have a bud stand on it and run it up and down past the sticky spot. will probably clear up.

Will give it a try later this week. Seems odd that both would do it at the same time, but have eliminated most causes except stuck rams at near same position. Will post results Thursday.

they are completely seperate systems. in this case, the right hand doesn't care what the left hand is doing.

Air. Just run it up and down several times. Stand on it, etc.

I'm having the same problems with my Bravo Drive i think..

Mines goes all the way up with no problem, and shuts off once it gets to the stop point, but when i try to bring it down, it goes about 1/2 way down and stops, so if i continue to press on the trim switch, it sounds as if, it's still engaged but it's not moving,,at times i do here some binding noises, but it comes and goes, and i cant pinpoint where its comin from..

i've been meaning to get to it, but weather has not been on my side.. does it sould like it has air in the lines, should i stand on it .. and it does not seem to have any play in it as well..

i have an electrical trim sender guage that does work either, so that didn't help.. could it be ram..but i do plan to disconnect the rams to c if theres any thing obstructing the drive.....Any other suggestions
