It is engineered for fresh water or raw water cooling systems and is molded (rather than bent) so it maintains full, unrestricted water flow through every curve of its shape while also simplifying installation compared to straight hose cut to fit.\u003c\/p\u003e\u003cp\u003eConstruction is EPDM tubing with a synthetic knit reinforcement layer, giving the hose resistance to heat, engine fluids, and the flexing loads typical of a running marine engine. Sierra molded hoses are built to OEM quality standards, so fit, form, and function match the original equipment hose they replace. The hose is finished in white and is designed as a direct fit for the specified engine applications, with no cutting or forming required at installation.\u003c\/p\u003e\u003cp\u003eThis hose fits 43L\/LX and MCM\/MIE V-8 (305 and 350 cid) engines and is specifically the thermostat-cover-to-starboard-manifold routing. It cross-references to Mercruiser part number 32-871171. Because this hose is designated for the starboard side, it is not interchangeable with the port-side hose, which carries its own separate Sierra and Mercruiser part numbers.\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 18-70932\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Molded Hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Thermostat cover to starboard manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e EPDM with synthetic knit reinforcement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 7.5 centimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 7.5 L x 34.3 H x 28.2 W centimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282145927\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282145927\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e 43L\/LX and MCM\/MIE V-8 (305 and 350 cid) engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser 43L\/LX engines\u003c\/li\u003e\n\u003cli\u003eMercruiser MCM\/MIE V-8 (305 and 350 cid) engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser 32-871171\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-70932 molded hose fit?\u003c\/strong\u003e The 18-70932 fits Mercruiser 43L\/LX and MCM\/MIE V-8 (305 and 350 cid) engines, routing coolant from the thermostat cover to the starboard manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich side of the engine does this hose go on?\u003c\/strong\u003e This hose, Sierra 18-70932, is a starboard-side application, running from the thermostat cover to the starboard manifold; it is not the same part as the port-side hose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Mercruiser equivalent part number for 18-70932?\u003c\/strong\u003e Sierra 18-70932 cross-references to Mercruiser part number 32-871171.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-70932 hose made from?\u003c\/strong\u003e It is built from EPDM tubing with a synthetic knit reinforcement layer, giving it resistance to heat and engine fluids in a marine cooling system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-70932 hose weigh?\u003c\/strong\u003e The 18-70932 molded hose weighs 0.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this hose molded or a straight cut length?\u003c\/strong\u003e The 18-70932 is a molded hose, shaped to maintain full water flow through its bends rather than a straight hose that needs to be manually bent or clamped into shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-70932 hose?\u003c\/strong\u003e This Sierra molded hose is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this hose work on both fresh water and raw water cooling systems?\u003c\/strong\u003e Yes, the Sierra 18-70932 molded hose is designed for use on fresh water or raw water cooling systems on inboard\/outboard marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-70932 an OEM-quality replacement?\u003c\/strong\u003e Sierra molded hoses, including the 18-70932, are manufactured to OEM quality standards so fit, form, and function match the original hose being replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the 18-70932 hose?\u003c\/strong\u003e The 18-70932 ships at 7.5 L x 34.3 H x 28.2 W centimeters, with a hose length of 7.5 centimeters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-70932 include any hardware or clamps?\u003c\/strong\u003e The listing includes the molded hose itself (18-70932); hose clamps are not specified as included components.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988361588955,"sku":"SIE-18-70932","price":30.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-70932_lg__44904.1558130284.500.750.jpg?v=1785189042","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-70932-molded-cooling-hose-thermostat-cover-to-starboard-manifold-replaces-32-871171-fits-mercruiser-4-3l-5-0l-5-7l","provider":"Good Vibes Marina","version":"1.0","type":"link"}
