Seloc says 70-80 ft lbs on the newer models with the same sized nut. Because of the heat and motion, they will work loose anyway, so the cotter pin is always critical. Grease the shaft and splines, and check often for fishing line behind the thrust bushing.

Pin is vital, there again so is the rest !!!
Use a waterproof grease.

Right, that's one of many places that I don't mind the extra cost of Triple Guard Grease; it stays in place in spite of the heat and motion.
