Yamaha Cotter Pin – 91490-30025-00

A tiny pin can save you from an expensive tow. This genuine Yamaha 3 mm × 25 mm cotter pin locks castle nuts and clevis joints so they stay put when the seas kick up. Formed from marine-grade stainless, it resists salt corrosion and repeated bending, making it a dependable backup for steering links, propeller nuts, and trim-tab hardware. The chamfered tip slips easily through pre-drilled holes, and the pre-split legs spread smoothly with a quick squeeze of pliers—no wrestling, no frayed ends.

Why it belongs in every onboard toolkit

• Exact OEM size: 3 mm diameter and 25 mm length match Yamaha castle-nut specs—no trimming or oversized play.
• Stainless resilience: fights rust and pitting after months in a wet bilge.
• Smooth install: tapered tip and even splits speed up roadside-style fixes at the dock.
• Reusable strength: keeps its shape after multiple removals, unlike cheap hardware-store pins.

Swap in the 91490-30025-00 whenever you service your prop or steering linkages and cruise away confident that every critical connection is locked down for the long run.
