Just wondering where should I go from here, my trim and tilt drops on my 135hp black max merc. It a 1986 model, Ive had the end cap and supposably all o rings replaced and the thing still drops. (Right down, just not to the trim prods) Twice Ive been told that its the o rings on the manual override but they look fine and is as tight as it gets. The system has been drained, filled and bled but still drops. It must be a slight leak though, I just had the lower unit off and basically didnt drop at all, but with the extra weight of the l/u it does. I was just wondering what the next step would be, seeing I constantly am using the trim, on one hand I think its not even worth persuing, on the other hand Ive spent all this money with no result, any ideas???
