Filling power trim with oil

[WhitePerchHunter]

Help!! I just changed all seals and o-rings on all three pistons of the power trim on my 175 Yamaha. I am attempting to fill with oil but have a major air problem. How must I fill with oil to eliminate all the air. Thanks for any advice.

I believe the manual says to fill individual parts as you put them back together

I believe all three pistons need to be fully extended to top off the fluid. The engine should be held up by the mechainical linkage when doing so. Trimming up and down once most/all the fluid is in should flush out any air..
