The tilt ram on my outboard is leaking terribly so I bought an o ring kit and pulled the tilt trim assembly off the motor. I borrowed the proper spanner from a friend to remove the end of the cylinder but it won't budge. Also every stainless bolt that is in a tapped hole in the diecast assembly seems to be hopelessly frozen. I'm the first person to try to turn these bolts since it left the factory. I'm afraid of shearing them. Any suggestions other than soaking in a penetrant and hoping for the best? Motor is a 1999 Johnson 200. As a worst case suggest a mechanic or where I might find a used replacement that is in decent condition.
