Because it’s discontinued, it’s worth ordering as a spare at the same time if the engine is a long-term keeper — once stock is gone, sourcing this pulley becomes difficult.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issues:\u003c\/strong\u003e The most frequent mistake is not confirming the groove count before ordering. A 3-groove pulley from a similar engine looks nearly identical but will cause immediate belt misalignment. The second common issue is assuming the pulley is the problem when the water pump bearing has actually failed — a failed bearing causes wobble that damages the pulley and belt, so always inspect the pump before ordering a replacement pulley.\u003c\/p\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/mercury-807730t-crankshaft-pulley-mercruiser-gm-v6-v8-serpentine\"\u003eMercury 807730T Crankshaft Pulley — MerCruiser GM V6 \u0026amp; V8 Serpentine\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-seawater-pump-pulley-8m0150724\"\u003eMercury MerCruiser Seawater Pump Pulley — 8M0150724\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-power-steering-pump-pulley-8m0150723\"\u003eMercury MerCruiser Power Steering Pump Pulley — 8M0150723\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-idler-pulley-864625t\"\u003eMercury MerCruiser Idler Pulley 864625T — 6-Groove Serpentine, 4.25\" OD\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/merc-1261\"\u003eMercury MerCruiser Serpentine Belt \u0026amp; Pulley Kit — 8M0150824\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-quicksilver-serpentine-belt-865615q04\"\u003eMercury MerCruiser Quicksilver Serpentine Belt 865615Q04\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/marisolmarine.com\/products\/mercury-quicksilver-865615q06-mercruiser-serpentine-belt\"\u003eMercury Quicksilver 865615Q06 Serpentine Belt — MerCruiser V8 5.0L–8.2L Sterndrive\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/section\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563858755620,"sku":"42799","price":104.72,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/6de8cb61-5c02-43be-84e7-528882d5cf20.png?v=1777483567"},{"product_id":"merc-267","title":"Mercury MerCruiser Quicksilver 428611 Brass Pipe Plug — 3\/4\"-14 NPT","description":"\u003csection class=\"product-description\"\u003e\n\n\u003ch2\u003eMercury MerCruiser Quicksilver 428611 — Brass Pipe Plug, 3\/4\"-14 NPT\u003c\/h2\u003e\n\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e428611 (service format: 22-428611)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCurrent OEM Replacement\u003c\/th\u003e\n\u003ctd\u003e8M0204679 (22-8M0204679)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003e428611\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMercury \/ Quicksilver (OEM)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eBrass Pipe Plug (Fitting)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eThread\u003c\/th\u003e\n\u003ctd\u003e3\/4\"-14 NPT (.750-14)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eBrass\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eDimensions (pkg)\u003c\/th\u003e\n\u003ctd\u003e1.00\" × 1.00\" × 0.58\"\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003eapprox. 60 g (0.13 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eHTS Code\u003c\/th\u003e\n\u003ctd\u003e741220\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eAftermarket Cross-References\u003c\/th\u003e\n\u003ctd\u003eSierra 18-4265 \/ GLM 21896 \/ GLM 22032\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eOverview\u003c\/h2\u003e\n\u003cp\u003eMercury 428611 is a genuine OEM brass pipe plug with a 3\/4\"-14 NPT thread, used across a wide range of Mercury Marine and MerCruiser assemblies including sterndrive transom assemblies, cooling system ports, exhaust components, engine blocks, and jet-drive applications.

The key detail customers miss is that the 43033 reference has been superseded by 430331, and the new part may look different while functioning identically. Because Mercury uses multiple similar gaskets in the same pump stack, confirm the diagram position (cover-to-face-plate) before ordering to avoid receiving the wrong gasket. Customers who order this part in isolation without replacing the impeller and face plate often return for a second service soon after — a complete water pump kit is typically the better value for anyone with the pump open.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the old gasket?\u003c\/strong\u003e\u003cbr\u003eNo. Once compressed and disturbed, gaskets do not re-seal reliably.

A blown high-current fuse is a symptom, not the root problem — replacing the fuse without finding the cause typically results in a second failure, sometimes with additional wiring or component damage. Check the protected circuit (trim pump, power steering, charging, or starting system) for shorts, loose connections, or failed components before putting the boat back in service. Mercury uses the same fuse housing style in multiple amperage ratings, so always order by part number (79023T10), not by appearance alone.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use the 90-amp or 55-amp fuse assembly if the 110-amp is unavailable?\u003c\/strong\u003e\u003cbr\u003eNo. The fuse rating must match the circuit’s wiring diagram.
