I have a 1993 85 HP Yamaha on which I'm having trouble w/ the power tilt and trim. Motor will go down but not up. Consequently, it is all the way down now and I can't trailer it anywhere for someone to look at it becasue the skeg will drag the road when the motor is all the way down. When I try to trim it up I hear a "click" so something is engaging but the trim does not move the motor up. Also, I can't figure out how to "release" the entire tilt and trim mechanism so that I can manually tilt the motor up so that it can be trailored to a repair facility. Can someone help me understand how this tilt and trim is put together and how I might disassemble or disengage it so that I can trailer the boat to a repair facility. I've looked at it over and over and it all appears to be sealed to me.
