I'm betting that you find a sheared pin when you take your coupling apart. The squealing occurred when there was enough torque applied to the shaft to make the propeller turn slower that the coupling. In other words, it couldn't keep up because of the resistance of the propeller.

I sure hope not. We were motoring easy, about 4 knots, pulling a dingy, not much for waves. Don't think we hit anything or got cought up with anything, we just lost power.
How often do these pins shear? is there standard sizes standard to buy new ones? My shaft is bronze (possibly old) and when the new engine was put in they used a stainless pin..corrosion? I just hope I can get that coupling apart to see. I also expect that driving a broken pin out could be a difficult. Although, a broken pin is better than a broken shaft.
