X 13-7\/8 in.","description":"\u003cp\u003eThe Sierra 18-3601 is a Gimbal Housing Water Feed Hose built for Mercruiser I\/O cooling systems where the thermostat housing connects to the port exhaust manifold. It is molded from rubber to handle continuous exposure to raw water and engine heat while routing coolant flow through the gimbal housing water feed circuit. The hose measures 5\/8 inch in diameter and 13-7\/8 inches in length, matching the original equipment dimensions so it installs as a direct fit without modification. Its white rubber construction resists the cracking, hardening, and leaking that commonly develop in aging OEM hoses from prolonged heat cycling and saltwater or freshwater exposure. As a Sierra replacement part, it is manufactured to meet or exceed the performance of the original equipment hose it replaces. This hose is a straightforward wear-item swap for boat owners and marine technicians performing cooling system maintenance, and it directly replaces Mercruiser part numbers 32-32461 and 32-32461A1. Keeping this hose in good condition is important, since a cracked or split water feed hose can allow air into the cooling system or let coolant escape, leading to overheating.\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 18-3601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Gimbal Housing Water Feed Hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 13-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\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 0.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 32-32461, 32-32461A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e32-32461\u003c\/li\u003e\n\u003cli\u003e32-32461A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3601 hose connect?\u003c\/strong\u003e The Sierra 18-3601 is a gimbal housing water feed hose that routes from the thermostat housing to the port exhaust manifold on applicable Mercruiser I\/O engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the 18-3601 hose?\u003c\/strong\u003e It measures 5\/8 inch in diameter and 13-7\/8 inches in length.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the 18-3601 replace?\u003c\/strong\u003e It replaces Mercruiser part numbers 32-32461 and 32-32461A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3601 a direct OEM replacement?\u003c\/strong\u003e Yes, the 18-3601 is manufactured to meet or exceed the specifications of the original Mercruiser 32-32461 and 32-32461A1 hoses it replaces, so it installs in place of the OEM part without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-3601 hose made from?\u003c\/strong\u003e The 18-3601 gimbal housing water feed hose is made from white rubber designed to withstand engine heat and continuous water exposure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3601 hose weigh?\u003c\/strong\u003e The Sierra 18-3601 weighs 0.38 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my water feed hose needs replacing?\u003c\/strong\u003e Signs that the 18-3601 or a similar gimbal housing water feed hose needs replacement include visible cracking, hardening, soft spots, or coolant leaks around the thermostat housing to exhaust manifold connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3601 come with hose clamps?\u003c\/strong\u003e The 18-3601 listing covers the hose itself; clamps are not specified as included components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-3601 is a genuine Sierra marine part manufactured to OEM-equivalent standards as a replacement for Mercruiser 32-32461 and 32-32461A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere on the engine does the 18-3601 hose install?\u003c\/strong\u003e It runs from the thermostat housing to the port side exhaust manifold on applicable Mercruiser I\/O cooling systems.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988154626267,"sku":"SIE-18-3601","price":90.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3601_lg__41516.1558125767.500.750.jpg?v=1785187988","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3601-water-intake-hose-5-8-x-13-7-8-for-mercruiser-sterndrive-gimbal-housing-water-feed-hose-replaces-32-32461-32-32461a1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
