I have a 2009 Yamaha 115 4-stroke. Over the past few months I noticed that there was a small leak out of the trim pistons so I decided to finally replace all the seals on both trim pistons and the tilt ram. With the right parts, the seal replacements was relatively easy. However....
I cannot figure out how to bleed the unit of all the air. I have tried several combinations of cycling through underpower, using the pressure release value, etc. and still cannot get all the air out of the system. I've talked to a few local mechanics who echo all the YouTube videos I have watched.
I am at the point where I think either (1) the new seals installed are not seated properly or (2) they are faulty seals. Before I go and replace the work I just completed I was hopeful that someone on this forum may have a tip/trick I have not tried yet.
Thank you for the insight.
