The Sierra 18-3735-9 is a marine-grade cotter pin sold as a package of 10, sized 5/32 x 1-3/8 inches. Cotter pins like this are used to lock castellated nuts and clevis pins in place on outboard drive and propeller hardware, preventing the nut from backing off under vibration and load. Each pin is made of stainless steel for corrosion resistance in the marine environment and finished in white.

This cotter pin is engineered to meet or exceed the quality of the original equipment part it replaces, and Sierra supplies OEM engine manufacturers and boat builders with parts of this same specification. It fits Suzuki outboards including the DT9.9 & 15C, DF9.9 & 15, and 8 & 9.9C Oil Injected models, and replaces Suzuki OEM numbers 09204-03003 and 09204-03004. Buyers replacing a lower unit, propeller nut, or shift linkage cotter pin on these Suzuki outboards can use this part directly.
