Prop Shaft Strut Replacement
Last winter when my boat was hauled out I addressed the loose strut. I was not about to start tearing out the glassed area above it so instead I drilled three holes on each side from under the hull up into the area where the strut is located.
It appears that the strut is shaped as an inverted Y with the flanges going to either side. I drilled 1/8" holes up through the hull until I actually hit the flanges. I drilled about 3 holes on each side so I could get more epoxy inside with a plastic syringe. I injected the epoxy until it to started to escape out of the other holes. At that time I inserted a small screw into each hole to stop the epoxy from running out.
I was surprised how much of a void there is based on the amount of epoxy I injected in. The next day I removed the screws and filled the dimples with marine putty before the new bottom paint went on. The result is a much stiffer strut with not much work involved.
I would like to see what Catalina suggests for such a repair.

Tom, that seems like an
awfully permanent repair. It would be nearly impossible to remove any or all
parts of the strut were ever damaged.
