Prop Nut (Pack Of 5) 18-3707-9 (118-3707-9) Sierra Marine Engine Parts Sea Star Solutions It refers to the use of two different-sized nuts to secure a propeller to a propeller shaft. It is a common practice regardless of whether the boat is a sailboat or a powerboat, twin-engine, or single engine, though some propellers are secured with single nuts and split pins or more elaborate fittings that incorporate shaft zinc. 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.
