OMC 800 outdrive. The tilt motor is working but it is making some hidious noises from within. I've taken all the bushing and gears outof the housing and removed the top worm gear. The rod that the worm gear slides onto seams to be broke way up in. I can take out about 5 inches but have no idea on how to get to the other end of the rod. I think it goes right up into the 12 volt motor but I don't see how to get the 12 volt motor out. Any idea's?
