Evinrude Etec E150DPXAAB 2012 150HP motor power tilt and trim stuck in down position

Hi,

I have an Evinrude Etec 150HP motor with power tilt and trim hydraulic unit.

The motor is tilted in the down position and I cannot get the power tilt and trim unit hydraulic pump motor to run. I have checked
- that there is 12V coming out of the relay to the motor blue and green wires
- I have even connected 12V directly to the motor plug in both polarities but the motor will not turn
- The resistance of the motor seems very high > 130kohms i.e. seems open circuit
- I have checked that the limit switch circuit is closed
The main issue I am having is that I cannot get the manual release screw to turn. I have sprayed several types of anti-corrosion sprays like Corrosion X and Shift Ya Bastard and also tried heating the screw and / or case or the hydraulic pack around the manual release screw and then using a manual impact driver but it just isn't turning. The head is getting pretty stuffed up too (see pic).

At this point, I'm just keen to get the engine tilted so that I can replace the power tilt and trim unit or just the motor.

A mechanic I spoke to said that to move the boat he could take the propeller shaft / gearbox off.

I was wondering whether anyone could tell me whether if I took the lower pin that goes through the hydraulic tilt unit out and also the other pin that looks like just there to restrain things if needed - both outlined in pic - whether I could then tilt the whole assembly up or whether it would clash with something else? Also, am wondering how you get a pin like shown in position 1 out…. It has kind of a circlip but I have never seen one like it - it has no bits to pull apart - any advice appreciated.

I am open to any other suggestions that would help me get this unit fixed.
