This selection of Yamaha‑compatible propeller hardware covers the essential fasteners that secure your prop to the prop shaft: stainless steel and brass castle nuts, flat washers, thrust spacers, and stainless split pins. Ideal for routine propeller changes, lower unit servicing, or emergency repairs at the ramp, each kit is organized by engine horsepower and stroke type so you can grab exactly the parts that match your outboard. Compatible with Chinese‑market Yamaha outboards and other domestic engines using the same prop shaft dimensions, these kits deliver a factory‑spec fit without the dealer price tag.\u003c\/p\u003e\n\u003cdiv class=\"gbs-warning-box\"\u003e⚠️ \u003cstrong\u003eAlways replace the cotter pin:\u003c\/strong\u003e Reusing a bent or corroded split pin can lead to prop nut loosening and propeller loss.

If you're replacing the entire propeller assembly or your spacer shows wear, choose the full kit to replace everything at once.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Can I reuse the old cotter pin after removing the propeller?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: Always replace the cotter pin with a new one. Old pins can develop hidden stress cracks and may snap or fall out, allowing the castle nut to back off and the propeller to come loose. A fresh stainless pin is included in every kit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Do these kits fit non‑Yamaha Chinese outboard engines?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: Many domestic Chinese outboards share similar prop shaft dimensions with Yamaha designs. Compare your existing hardware size and thread pattern to the photos. The 4‑stroke 40–60HP universal kit and small HP kits are most commonly cross‑compatible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: How tight should I torque the castle nut?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: Tighten the nut snugly by hand, then use a wrench to align the next castle slot with the cotter pin hole. Do not over‑tighten, as this can distort the thrust washer and cause prop binding. Always insert the cotter pin and bend the legs to secure it.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Why are some kits brass and others stainless steel?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: Brass castle nuts are preferred for saltwater use because they resist seizing on the stainless prop shaft. Stainless cotter pins provide the necessary strength and corrosion resistance for the retaining pin.
