Up until this year my trim has worked without any problem. But recently it just stopped working all together. I rewired my solenoids, they work perfect. The trim motor still runs, for both up and down, but the engine does not go up or down. I then lifted the motor up and down and noticed that the manual release valve was leaking and also noticed that the o ring had worn out and fallen onto the ground. I would just replace the o ring but the problem is, I can't get the screw out. You seem to need a special tool to take it out and get an o ring over it, you cannot just unscrew it. My question is, would just a faulty o ring on the manual release valve really cause the engine to not lift up or down? or would the engine lift up slowly and then just sag down? All other o rings are fine, fluid is full. I am ver confused and frustrated and ready to explode!!! Any help would be exellent. Anything at all. I was considering taking the entire unit apart to get the o ring in, but is their a special tool that can take that screw right out of the manual relase?????<br />HELP!!<br />Thanks<br />Craig
