Rebuilt power trim unit not working
hello everybody,,,i just rebuilt my power trim unit, got it back on the boat and,,,,it dont work,,i can hear the motor run when i push in the switch,,1st time i hit the switch the 2 lower piston arms came up but when i relased the lock on the motor and tried to lower it it wouldnt go down or up, so i opened the maual release and the motor came down to the lower pistons and stoped,they wouldnt push in,, again up or down i can hear the motor run but nothing moving, could it be a fluid problem as in to much ? the trim unit is on a 1989 johnson 120hp,,,thanks for the help,and happy easter OLOR]

Re: Power trim unit

It should be filled when in the full up position.
If it's still part way up try to add fluid &
hit the up button to bleed out the air.
Cycle full up & Down a couple of times &
Recheck level when all the way up.
