150 mercury power trim manual release not functioning

[mgoff]

150 mercury power trim manual release not functioning. Backed the screw 4 full turns and can't manually tilt the motor up. Service manual said don't back it out more than 4 full turns.

You might have to crack the hydraulic lines to tilt it up.
Sorry, can't help with the release not working.
