I have a 1980 115 HP Johnson and replaced the power trim motor. The power trim works great until the fluid leaks out in about a month or so, then you have to refill it. It appears to seep out around the "o" rings on the main hydraulic piston. Can anyone explain or send me a step by step on how to change out the "o" rings, what if any special tools I need and where is the best place to order them? The mechanics manual i have just covers the Motor repairs. Thanks!!!
