Confirm the customer’s blower outlet diameter before selling — 3\" and 4\" are the two most common sizes, and they are not interchangeable without adapters. The 50-foot roll is ideal for shops doing multiple installations or for vessels with long hose runs from the engine compartment to the through-hull vent.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSafety Note:\u003c\/strong\u003e Engine compartment ventilation hose must be flame-retardant per ABYC and USCG standards for gasoline-powered vessels. This hose meets that requirement. Do not substitute standard bilge hose or plain PVC in blower applications — they are not rated for fuel vapour ventilation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCutting \u0026amp; Installation:\u003c\/strong\u003e Wire-supported hose can be cut with a utility knife — score around the circumference and bend to snap the wire, then trim the vinyl cleanly. Secure with stainless hose clamps at each end. Avoid sharp bends that could kink the wire and restrict airflow.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51215079243812,"sku":"50-23811","price":62.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/50-23807_897d785c-41dc-469a-9387-01cf68d2300b.jpg?v=1786146058","url":"https:\/\/marisolmarine.com\/products\/seachoice-vinyl-blower-hose-402-series-4in-x-50ft-black","provider":"Marisol Marine Company","version":"1.0","type":"link"}
