Re: OMC sea drive tilt/trim
This must be Seadrive T/T problem week...lol
I just had the same problem with mine, stuck in the down position and couldn't move the boat. Couldn't get to the relief because you couldn't access anything with the engine down.
I removed the cover (vertical cover with the 4 screws that is attached to the pivoting mount) attached a lift to the lower unit and could than access the four bolts that hold the trim cylinder to the motor bracket, removed the bolts and was than able to lift the motor and block it with a 4x4 for transport. Once this trunion is removed you can lift the engine very high, just make sure your wires and fuel lines don't get snagged or pulled to hard while lifting.
Good luck!
