This kit bundles the four pieces needed to properly mount and secure your propeller in one package: a prop nut, a cotter pin, a washer, and a spacer, so you are not hunting down individual hardware pieces separately. The nut is manufactured from metal with a polished gold finish and a hexagonal shape, sized to an M14 thread with a 14 millimeter compatible groove diameter, and rated to an industrial grade standard for durability in continuous marine use.\u003c\/p\u003e\u003cp\u003eSierra engineers this hardware to meet or exceed the performance of the original equipment it replaces, and the company supplies parts to OEM engine manufacturers and boat builders. The kit is designed as a direct cross-reference for Suzuki outboard prop nut assemblies, making it a straightforward replacement when your existing prop hardware is worn, corroded, or missing pieces.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
