Power Trim Stuck/Blockage

Hi All,

I have a Mercury Power Trim off a 60 hp, 3 wire unit like this one
T-T.JPG

The unit will not move up or down, I get a small amount of down movement if I help push on it.
I have stripped the entire T/T and checked/services all parts. I cannot find anything wrong. The only thing I noticed was that if I blow compressed air into the below hole it is completely blocked. Ive worked out that this hole feeds the bottom of the cylinder and pushes the ram up. Is it normal that this hole is completely blocked?
Does anyone have any advise about this or anything else I can check. The motor is strong so its not that. It seems like the bottom passage that pushes the ram up is blocked

Dani
