It seals the connector plate where the power trim hydraulic hoses meet the housing, preventing hydraulic fluid seepage that can develop as the original gasket ages and loses its seal. This gasket is built to meet or exceed the specifications of the original equipment part it replaces, giving boat owners a reliable, drop-in option when servicing the power trim system during routine maintenance or when addressing a fluid leak at the connector plate.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward for anyone already accessing the power trim hose connector plate: the old gasket is removed, the mating surfaces are cleaned, and the Sierra 18-0342 is fitted in its place before the connector plate hardware is reinstalled and torqued. Because it directly replaces the OEM Mercruiser 27-476441 and 27-47644 connector plate gaskets, it restores the original seal without modification to surrounding components.\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 18-0342\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Power Trim Hose Connector Plate Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999873309\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e Mercruiser 27-476441, 27-47644\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser 27-476441\u003c\/li\u003e\n\u003cli\u003eMercruiser 27-47644\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0342 gasket fit?\u003c\/strong\u003e The Sierra 18-0342 is a power trim hose connector plate gasket, used where the power trim hydraulic hoses connect to the connector plate on applicable MerCruiser sterndrive units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0342 the same as Mercruiser 27-476441?\u003c\/strong\u003e Yes, the Sierra 18-0342 is a direct replacement for the Mercruiser 27-476441 and 27-47644 connector plate gaskets, built to meet or exceed the original equipment specification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0342 gasket weigh?\u003c\/strong\u003e This gasket weighs 0.01 pounds, consistent with its small, thin construction as a single connector plate seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need any special tools to install the 18-0342 gasket?\u003c\/strong\u003e No special tools are required beyond what is already needed to access the power trim hose connector plate, since the 18-0342 is a direct fit for the hardware it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-0342 an OEM or aftermarket part?\u003c\/strong\u003e It is an aftermarket gasket manufactured by Sierra that is built to meet or exceed the quality of the original equipment Mercruiser 27-476441 \/ 27-47644 gasket it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the package with part 18-0342?\u003c\/strong\u003e The 18-0342 ships as the connector plate gasket itself, sized to seal the power trim hose connection at the connector plate.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this gasket be reused after removal?\u003c\/strong\u003e No, gaskets like the Sierra 18-0342 are designed for one-time use and should be replaced with a new gasket any time the connector plate is disassembled.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace the power trim hose connector plate gasket?\u003c\/strong\u003e A worn or hardened connector plate gasket can allow hydraulic fluid to seep at the connection point; installing a new Sierra 18-0342 restores the seal and stops the leak.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the UPC 030999873309 confirm genuine Sierra packaging?\u003c\/strong\u003e Yes, UPC 030999873309 corresponds to the genuine Sierra 18-0342 Power Trim Hose Connector Plate Gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs one 18-0342 gasket enough for a complete repair?\u003c\/strong\u003e The Sierra 18-0342 is supplied as a single connector plate gasket, matching the one-piece original equipment seal it replaces.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988065464539,"sku":"SIE-18-0342","price":1.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0342_lg__59662.1558118385.500.750.jpg?v=1785188418","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0342-power-trim-hose-connector-plate-gasket-replaces-mercruiser-27-476441-pkg-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
