While I was changing my prop over the weekend I notice something strange. When I applied downward pressure to loosen the nuts the out-drive move down about 15degrees. I than tried moving the drive up and down manually and was able to move it 15-20degrees up and down. I never noticed this before. I would not think that I should be able to move it by hand. I did go out over the weekend and did not notice any problems tripping the boat. It is a Bravo I out-drive.

Where is the slack coming from?? Lower swivel pin?? Do you have external steering?? Is it slop in the trim system or the gimbal ring itself??

The slop is in the trim rams, everything else is tight. Wondering if i have some air in the power trim system and if i do how do i bleed the system.

The trim rams should bleed any air out by running them all the way up and down a few times.

Mine did the same thing. I had the drives serviced this year and the mechanic said that I was missing some kind of "spacer". He tried to explain it to me over the phone but I still have no clue. I don't see some new "spacer" that wasn't there, but my drive doesn't move anymore either

where the trim rams bolt to the rear of the drive (1 long bolt
through both sides) take this bolt out along with the bushings inside should be a with half moon white spacer.
