It supersedes 18663, which was catalogued earlier simply as a washer, so the current part is the locking tab type rather than a plain one. No thread size or fitment is published against it — where the propeller hardware does give a size, 873475 is the M16 tab washer, 873488 the M20 and 873506 the M24.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Marine Propulsion group tab washer\n \u003c\/li\u003e\n \u003cli\u003e\n  0.020 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Supersedes 18663, catalogued earlier as a washer\n \u003c\/li\u003e\n \u003cli\u003e\n  No published thread size — order by part number or measure the nut\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Locks the nut it sits under, with a tab bent up against a flat so the nut cannot turn back in service.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Tab cracked or broken off at the bend\n \u003c\/li\u003e\n \u003cli\u003e\n  Washer found flattened where the nut has moved\n \u003c\/li\u003e\n \u003cli\u003e\n  Corrosion or erosion around the bore\n \u003c\/li\u003e\n \u003cli\u003e\n  Nut slack on inspection\n \u003c\/li\u003e\n \u003cli\u003e\n  Vibration or knocking from the assembly it retains\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Tab washers are single use — fit a new one whenever the nut is disturbed\n \u003c\/li\u003e\n \u003cli\u003e\n  Measure the nut before ordering, as no thread size is published against this washer\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔄 Supersession \u0026amp; Cross Reference\n\u003c\/h2\u003e\n\u003ch3\u003e\n OEM Supersession Chain\n\u003c\/h3\u003e\n\u003cul\u003e\n \u003cli\u003e\n  873497 → Supersedes 18663\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\n OEM \/ Related Numbers\n\u003c\/h3\u003e\n\u003cul\u003e\n \u003cli\u003e\n  18663 earlier number superseded by this part\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta part\n \u003c\/li\u003e\n \u003cli\u003e\n  Brand new\n \u003c\/li\u003e\n \u003cli\u003e\n  Supplied in original or equivalent packaging\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53379809345828,"sku":"T303921","price":20.81,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_3b04aa3a-bf69-454f-92c2-7becb8cee21b.jpg?v=1777119809","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/873497-tab-washer-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
