I recently purchased a nice 1970 Mercury 650 Thunderbolt and it came with this steering system connected. I have a better steering system on my boat, so I'd like to remove this one, but darned if I can figure out how to get it off my motor! It appears, that if I remove the large nuts on both sides of the motor mount that has the steering piston going through it, the motor might fall off. I have the Seloc On-line repair manual, and it covers the steering system, but it does not show the cable from the steering mechanism to the motor.
