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.

Prop Shaft Strut Replacement - Another Source
I recently had to replace a cracked and slightly corroded strut on my 1982 C30.  Catalina was unable to find a replacement for that year as it seems that around '82 Catalina used a slightly different strut. I eventually had to get one cast from my original. It is an exact copy except that I had the cutlass bearing tube beefed up a bit to prevent future cracking. So for those of you that have that vintage of Catalina with a similar problem, I suggest contacting Marine Hardware in Redmond, Washington for a replacement. Don Starbuck at www.marinehardware,com
