Similar MerCruiser engines use different hoses for inline drives, port-side connections, and 6-inch-riser configurations — matching the closed-cooling system diagram is essential. A common mistake is selecting a hose by engine displacement alone without confirming drive type and riser height. If the customer is unsure of their riser configuration, have them measure riser height or check the engine tag before ordering.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324674146340,"sku":"32-864544","price":79.49,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/282a1ddc-0bc6-43ed-950e-9f4bc50a7776.png?v=1788219753","url":"https:\/\/marisolmarine.com\/products\/default-59","provider":"Marisol Marine Company","version":"1.0","type":"link"}
