It creates a watertight seal at the pickup\/connection point in the raw water cooling circuit, helping prevent leaks and water intrusion that can lead to corrosion or reduced cooling performance. Made from rubber for flexibility and resistance to the marine water environment, this seal is a low-cost, high-frequency maintenance item that should be replaced any time the water pump connection is disassembled for service, or as part of routine cooling system maintenance. It is sold as a package of 2, so buyers have a spare on hand or enough for both connection points in a single service job. This seal directly replaces OEM part number 814356 and is designed to fit Volvo Penta AQ200, AQ250, AQ270, AQ275, AQ280, and AQ290 engines. Installing the correct rubber seal at this connection point is a simple but important step in keeping the raw water cooling system sealed and functioning properly, and using the Sierra 18-2939 ensures a fit and material equivalent to the original equipment part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-2939\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Rubber Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Water Pump Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 814356\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo Penta AQ200\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ250\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ270\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ275\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ280\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ290\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e814356\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2939 rubber seal used for?\u003c\/strong\u003e The Sierra 18-2939 is a rubber seal that fits at the water pump connection on Volvo Penta AQ series sterndrive engines, sealing the raw water cooling circuit at that connection point to prevent leaks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Volvo Penta engines does the 18-2939 seal fit?\u003c\/strong\u003e This rubber seal is designed to fit Volvo Penta AQ200, AQ250, AQ270, AQ275, AQ280, and AQ290 engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2939 replace OEM part 814356?\u003c\/strong\u003e Yes, Sierra part number 18-2939 directly replaces OEM number 814356.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many seals come in a package?\u003c\/strong\u003e The Sierra 18-2939 rubber seal is sold as a package of 2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-2939 seal made from?\u003c\/strong\u003e It is made from rubber, chosen for its flexibility and ability to hold a watertight seal in the marine cooling environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2939 rubber seal weigh?\u003c\/strong\u003e The package weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should this rubber seal be replaced?\u003c\/strong\u003e The 18-2939 should be replaced any time the water pump connection on a compatible Volvo Penta AQ engine is disassembled for service, or when the existing seal shows signs of hardening, cracking, or leaking.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2939 an OEM or aftermarket part?\u003c\/strong\u003e The 18-2939 is a Sierra aftermarket rubber seal manufactured to replace OEM part 814356 on the applicable Volvo Penta AQ engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering the 18-2939?\u003c\/strong\u003e Ordering the 18-2939 provides a package of 2 rubber seals for the water pump connection on compatible Volvo Penta AQ engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill one 18-2939 package be enough for a full water pump connector service?\u003c\/strong\u003e Since the 18-2939 ships as a pack of 2, most single-engine water pump connector services on a Volvo Penta AQ200-AQ290 engine can be completed with one package.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988133228763,"sku":"SIE-18-2939","price":11.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2939_lg__84350.1558123871.500.750.jpg?v=1785189081","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2939-rubber-seal-for-volvo-penta-water-pickup-connection-replaces-814356-fits-aq200-250-270-275-280-290-pack-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
