What would be the shear pin size for 1950 HD25? Are some available, or do most make them from rod stock?

February 7, 2019 at 4:45 pm #166275Part number is 004372. But I can’t find my size chart. I’m guessing (assuming) that they are stainless steel, since the motor has a rubber shock absorber ring in the propeller. Most of us make our own.

July 19, 2019 at 2:49 pm #179183I was toying around with the idea of using a drill bit, though that would rust over time and is highly inflexible which may cause other things to fail if something goes wrong. In any case, the drill bit that fit the best is a 1/8″, if that helps. I will attempt to find some brass rod stock and cut one to length, or I may go the brass screw route that was suggested above.
