Are you going to do all the repair yourself? To take off the gimble, if it has never been done before, you have to buy a kit with a templet that shows you where to drill. You might have noticed, on some outdrives, there are two large hex screws on each side at the top of the gimble housing. That means those outdrives gimbles have been removed. That means the upper gimble nut was worn and needed a new gimble. I have seen one time where someone had transom rot and needed this work done. The engines have to be removed, as well as the outdrives of course. Then the rot removed and the transon rebuilt with new wood and glass. It is an extensive job. I am pretty handy with maintenance, but I dont think I would attempt that job on my own. Good luck.
