OK - I have read a lot of the messages regarding the array of tilt / trim issues with the Force outboards. Here is my situation.<br /><br />I just bought a 1987 Bayliner with a Force 125. The tilt and trim run up and down fine when it is on the trailer or not moving. When I am under power (moving forward), I can't get the engine to either trim or tilt. Also, when I do get it lifted, it does have the ever prombematic issue of slowly dropping (very slow).<br /><br />So, I read a number of the posts here and decided to be adventerous and disasemble the unit. First off, the fluid was all milky (the plug was stipped and I think water was getting in. That is being retapped this weekend). I disconnected the lines and removed the lower pump unit. I then decided what the heck, let's pull the four bolts holding togeher the top piece on the pump unit. Inside, I found three ball bearing, three springs (two tall one short. One one tall, there was a valve plug? on each end..) and four tiny washers. I cleaned up everything and put it back together (but could no figure out where the washers went). Well, the pump still moves the engine up and down, but I have not been in the water yet, and there is still the slow leak down.<br /><br />Finally.... here is my question.<br /><br />1) In one of the groves where the ball bearings sat, there was a scored (worn) section. I am wondering if this could be part of the leaking issue.<br /><br />2) I have read about the o-rings on the needle valve in the lower body. I have the old clip retainers not the allen heads. Any good suggestion for removing them. <br /><br />3) Where to those washers go?? Do I really need them?<br /><br />4) I am running 46 weight hydrolic fluid in the system, is that ok?<br /><br />5) Suggestions as to the cause of the working lift, but not when it is under forward motion?<br /><br />Thanks for all the help (sorry it was a bit wordy, just wanted to get out all the details).<br /><br />Mike
