Prop Nut - Sierra Marine Engine Parts - 18-3726 (118-3726)

The prop nuts keep the propeller tightly seated against the shaft taper. Because the propeller continuously pushes into the shaft due to the engine's power, prop nuts don't take much stress in a typical operation. There may be some load on the nuts in the other direction, but it is just momentary and nothing to be concerned.

Two different-sized nuts keep a propeller in place on a propeller shaft. The Prop Nut is a piece of hardware that helps your trolling motor run more efficiently, last longer, and be quieter. The ELIMINATOR Prop Nut stabilizes the prop by offering a contact point with a patent-pending design to reduce prop noise and vibration.

Over 6,000 maritime parts, tools, and components are available as Sierra aftermarket replacements. Sierra's products withstand tough marine environments and meet or exceed OEM specifications.
