Inspect the prop nut, thrust washer, spacer, hub components, cotter pin or retaining hardware, and propeller shaft threads while the propeller is removed. Tighten the propeller nut using the Mercury service procedure for the specific gearcase and hub system, then verify the locking washer seats correctly before returning the boat to service.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e13-423511\u003c\/strong\u003e — Mercury\/MerCruiser formatted part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e423511\u003c\/strong\u003e — Manufacturer part number\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003ePropeller hardware should be replaced when it no longer locks cleanly.
