The following technical infomation on the installation of the propeller shaft strut on Seidelmann sailboats was researched and provided by:

1 - I reacquainted myself with a fellow who worked at Seidelmann's 20+ years ago and he described how he recalled the struts were installed. I have tried to translate his explanation to a crude drawing (attached). Basically, it involves determining the proper position (?) along the underside of the skeg - then grinding a flat spot on the bottom of the skeg so the flat mounting plate on the strut can be fit flush and the holes (he recalls it was 6) can be marked and pilot holes drilled into the f/g. Then the strut is epoxied and screwed to the skeg...and finally, using something like West System, the area is filled, faired, sanded, etc., to complete the job.I'm guessing if you carefully grind the f/g immediately surrounding the area where the strut attaches to the skeg, you will expose the flat plate...after that, good luck. If you cannot remove the screws in the normal fashion, you may have to drill them out - then fill the holes with epoxy and redrill to mount a new strut.
2 - Speaking of a new strut, I have emails out to a couple of marine products locations that may either be the Seidelmann supplier or know who it was. At the very least, I've located someone who says they can build you a new one if you can get all parts of the broken one to them to use to build a mold. If I can find the original supplier, one thing they will probably need to know is the shaft size (7/8", 3/4", 1", etc.) - assuming Seidelmann used different sizes on different boats. I know the S37 uses a 1" shaft, but not sure about the 299.
