It routes raw cooling water from the sterndrive through the transom assembly and gimbal housing into the engine cooling circuit. Over time the hose assembly becomes brittle, cracked, or restricted from heat cycling and age, reducing cooling flow and risking engine overheating. This kit replaces the complete hose assembly and all associated sealing and mounting components in one service.\u003c\/p\u003e\n\u003cp\u003eThis kit supersedes the earlier \u003cstrong\u003e32-43437\u003c\/strong\u003e.

The bell housing hose is a rubber component that lives in a hot, pressurized environment and cycles between dry and wet conditions every time the boat is used. Most failures happen when the hose has been in service for many years without inspection — the exterior can look intact while the interior has hardened and restricted flow significantly. The most common ordering issue is customers not confirming the drive model: this kit is Bravo and Blackhawk only. If the drive is an Alpha One or a different sterndrive family, a different hose assembly will be required. When this job is open, replacing the raw water pump impeller at the same time is good practice — both components serve the same cooling circuit and the labour overlap makes it efficient.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563914264612,"sku":"8M0090859","price":119.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/0f34cf65-8f94-42d9-8133-fb5aff305994.png?v=1773424469","url":"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-bell-housing-hose-kit-8m0090859","provider":"Marisol Marine Company","version":"1.0","type":"link"}
