Tilt and Trim will not go out (up)

I have a 1985 Johnson 115 Outboad motor on a Procraft Bass Boat. The boat<br />and motor have been sitting for a couple years (in storage) and I proceeded<br />to clean it up and get it running recently. After rebuilding the carb, and<br />lubing everything, she started up and ran great. Even had her out for 3<br />outings in one week. Just this past week I tried to launch her and found<br />that neither the tilt or trim would go up (out). After fiddling with it for<br />awhile and since I could not get the motor off the transit saver, I took her<br />home.<br />At home I loosend the manual release valve and I could pick the motor up off<br />the T-saver and bring the tilt piston in. Note: If I tighten the manual<br />release valve while motor is down, I cannot begin to budge the engine up,<br />although if I hold the engine up by hand and tighten the manual release<br />valve, it will not hold the engine up.<br /><br />After studying the hydraulic diagram that came with manual I purchased<br />awhile back, I took the Tilt and Trim unit out and found that the tilt<br />cylider will retract under power, but will not advance. I pulled the motor<br />out, it runs in both directions. I replaced the tilt/trim relief valve, to no avail. I am at the point, that at looking at the hydraulic diagram, there<br />could be a number of thing that cause this problem. What I need is some<br />sound advice as to how to narrow the possibilties. I would appreciate any<br />suggestions at this time.

This may be simple, but it worked for me. I had a similar problem. I obvioiulsy had a hydrolic fluid leak somewhere, because after I added hydrolic fluid it worked great.

Thanks for the feedback, but I am not losing hydraulic fluid externally. It appears that it may be bypasssing where it is suppose to go and is being directed back to the resovoir.

I had a similar problem on my 1992 Johnson 100hp. Here's what I did. I followed the wires from the switch buttons on the motor and found the relay housing. I removed the cover and reversed the relays, and that caused to to trim and tilt up but not down. I therefore reasoned that the problem was a defective relay. I took a relay out of a box on my F250 and plugged it in and the trim/tilt worked both ways. Then I had proof that the relay was the problem. I went to NAPA and purchased a new relay for $6. The only difference was that the bottom of the original relay was sealed with silicone, so I siliconed the new relay to "marinize" it. No problems all summer since the repair. Try to isolate the relay and you may solve your problem.

Thanks Larry, I will check that but I have a feeling that it may be something different based on the fact that, with the electric motor physically disconnected from the pump, I can see that the motor does switch rotational directions when I move tilt/trim switch from up to down.

DG - <br />Let us know what you find out. I'll file that away for future reference.
