Prop Nut (Pack Of 5) - Sierra Marine Engine Parts - 18-3705-9 (118-3705-9)


The prop nut, which holds the prop to the shaft, transfers the reverse thrust. Thus, many spacers are splined; and some are additionally cogged or pinned for different Mercury, Mariner, and Mercruiser applications. It is to operate with a surface tab washer and stop the nut from coming undone. Propeller nuts don't experience significant strain during routine operations because the propeller continuously presses against the shaft as a result of the engine's power. Two different-sized nuts hold a propeller in place on a propeller shaft. There may be a slight load on the nuts in the opposite direction, but it will only last for a brief period and is of no significance.
