Re: Mirage 30 - propellor shaft strut
If you are planning to remove the strut you will have to refair it on installation - so, grind the bottom paint off around the strut where it enters the hull. You will expose the existing fairing and determine if there is a flange that is thru-bolted through the hull, like the C&C installation. If thru-bolted remove the rest of the fairing material (might be able to pry it off with chisel) so you can access the bolt heads. Will need to do same inside to access the nuts/washers. A good telltale is if you can see a fine line in the the bottom paint around the strut.
Are you sure it is actually bent? If there are other M30's around do a visual comparison before taking on more work than necessary. Bending a cast bronze strut takes a lot of force. Have you ruled out misalignment, worn cutless?
