Tilt/Trim Not Working, Please Help!

[acoustics2010]

Hi all.
Firstly I have a 2000 Yamaha 70hp 2 stroke outboard.
It appears that my tilt/trim motor has completely stopped working.
I have tested the relay and all connections and tests good, second test will be the tilt/trim motor. Problem is I cannot access it
I turned the manual release screw clockwise to relieve the pressure so that I can tilt the outboard up and down manually by hand. What happened is the outboard went down and now will not go back up no matter how hard I try to lift it. I cannot find any reason why its not free to lift up but it just does not.
So my problem is now I cannot access my tilt/trim motor to try and fix and I cannot get my outboard up so trailering it to an outboard repair shop is out.
Please help, am I missing something?
Any info would be appreciated
Steve

if it went down it will come up.
may require you AND a buddy in the water but it will.
they even have a manual release on an F350 V8.
however it takes a fork lift to raise the engine.
don't ask how I know this.
if you remove the 10Ga blue and green wires from the trim relay.
take the GREEN wire to a good ground and the BLUE wire to a good 12V positive it should go up.
if not the motor is likely fried.
if the motor runs remember to close the manual valve.
