This hose carries raw water from the intake to the engine's cooling circuit, a critical connection point where cracking, hardening, or collapse can quickly lead to overheating. The 18-3602 measures 13 7\/8 inches in length with a 3\/4 inch outside diameter, sized to match factory routing without modification, and its universal fit design allows it to be trimmed or positioned to suit the specific installation.\u003c\/p\u003e\u003cp\u003eBuilt from glass-reinforced hose material in white, it is designed to withstand the flexing, vibration, and constant exposure to raw water and engine-bay heat that marine intake hoses see in service. Sierra manufactures this hose to meet or exceed the specifications of the original equipment part it replaces, and it is intended as a straightforward swap for aging, cracked, or collapsed intake hoses on covered drive applications.\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 18-3602\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Mercruiser Hoses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 13 7\/8 inches (3524 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter:\u003c\/strong\u003e 3\/4 inch (191 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e MR, Alpha One and Gen II drives\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282258818\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.47 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser MR sterndrive\u003c\/li\u003e\n\u003cli\u003eMercruiser Alpha One sterndrive\u003c\/li\u003e\n\u003cli\u003eMercruiser Alpha Gen II sterndrive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e32-41725-33\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat drives does the Sierra 18-3602 water intake hose fit?\u003c\/strong\u003e The 18-3602 is designed to fit Mercruiser MR, Alpha One, and Gen II sterndrive applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is this intake hose?\u003c\/strong\u003e It measures 13 7\/8 inches (3524 mm) in length with a 3\/4 inch (191 mm) outside diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM Mercruiser part number does the 18-3602 cross to?\u003c\/strong\u003e The Sierra 18-3602 corresponds to Mercruiser part number 32-41725-33.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the hose made from?\u003c\/strong\u003e The 18-3602 is made from glass-reinforced hose material in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3602 water intake hose weigh?\u003c\/strong\u003e It weighs 0.47 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a universal-fit hose or a fixed-length hose?\u003c\/strong\u003e The 18-3602 is a universal-fit hose, meaning it can be positioned or trimmed to suit the specific installation on MR, Alpha One, and Gen II drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3602 equivalent to the OEM Mercruiser part?\u003c\/strong\u003e Yes, Sierra manufactures the 18-3602 to meet or exceed the specifications of the original Mercruiser equipment part it replaces (32-41725-33).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace my water intake hose?\u003c\/strong\u003e A water intake hose like the 18-3602 should be replaced when it shows cracking, hardening, or collapse, since a failing intake hose can restrict raw water flow and lead to engine overheating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-3602 hose?\u003c\/strong\u003e The 18-3602 is white in color.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3602 include clamps or fittings?\u003c\/strong\u003e The 18-3602 is the water intake hose itself; clamps and fittings are not called out as included components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho makes the 18-3602 hose?\u003c\/strong\u003e The 18-3602 water intake hose is manufactured by Sierra, a supplier of marine engine parts to OEM engine manufacturers and boat builders.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988155052251,"sku":"SIE-18-3602","price":13.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-3602__87940.1737831198.500.750.jpg?v=1785188884","url":"https:\/\/www.goodvibesmarina.com\/products\/molded-marine-hose-for-mercruiser-5-0l-5-7l-replaces-32-73796-thermostat-cover-to-exhaust-elbow-sierra-18-3602","provider":"Good Vibes Marina","version":"1.0","type":"link"}
