If you have kept the reservoirs full and the cylinders have raised and lowered then it is bled. It self bleeds as the fluid passes through the reservoir when going up and down. As long as you have kept them full there is no way you can get air in the system through the reservoir.

Oil level is why I asked how level the pumps are mounted. Either way if they are tilted forward or back you could be sucking air into the line while running in choppy waters. I have to run mine over full with puketanks even though they are level just to keep from sucking air. Mainly on my tab pumps I'm always adjusting. And I run really thin oil in them to speed reaction time up
Thanks everyone that's been able to help so far.

That is my situation. Either that or using the force of the prop right as you come off plane.

the trim cyl has a LOT of power to raise the drive. has very little to lower the drive. there is a seal in the middle stops fluid from pressurizing both sides of the piston. if they aren't too corroded up, rebuild is cheap and easy.
