I have a 97' 225 yamaha sws2. Had to replace the seals and dust caps on the two trim pistons, the main is good. I am having a problem getting what i believe to be all the air out of the system. They trim up great but trim down very little if all. I have been raising it completely, opening the cap to release air, adding fluid (if needed), closing the cap, and releasing the manual let down screw and letting it all the way down. Repeat. Done it about a dozen times and it still is about the same... gets a little better but not much. Any recommendations that may help me out? Is it possible i have a faulty check valve in there somewhere causing them to not trim down? Any insight would be great, starting to get frustrated, thanks.
