It supplies the three components needed to properly secure a propeller to the prop shaft: a prop nut, a cotter pin, and a prop spacer. Each part in the kit meets or exceeds original equipment quality, so it installs and functions like the factory hardware it replaces.\u003c\/p\u003e\u003cp\u003eThe kit directly replaces OMC part number 175268, and each individual component cross-references to its own OMC part number, making it straightforward to confirm fitment against your outboard's existing hardware. The prop nut and spacer are metal with a machined finish, built to handle the repeated torque and vibration loads of propeller hardware. The cotter pin locks the prop nut in place to keep the propeller from backing off the shaft during operation.\u003c\/p\u003e\u003cp\u003eThis kit is intended for boat owners and technicians replacing worn, corroded, or lost propeller hardware, or servicing a propeller during routine maintenance. Because it bundles all three parts together, it saves the step of sourcing the nut, pin, and spacer separately.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-3717\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Prop Nut Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Prop Nut (18-3707, O.E. 319891), Cotter Pin (18-3743, O.E. 320785), Prop Spacer (18-4232, O.E. 323943)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999316387\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOutboard - Johnson\/Evinrude (OMC\/BRP) drive systems\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOMC 175268\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3717 Prop Nut Kit include?\u003c\/strong\u003e The kit contains a prop nut, a cotter pin, and a prop spacer, the three components needed to mount and secure a propeller on a Johnson\/Evinrude outboard prop shaft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-3717 kit replace?\u003c\/strong\u003e It replaces OMC part number 175268.
