{"product_id":"qbp878023","title":"Volvo Penta Extension - Volvo Penta (3853621)","description":"\u003cp\u003eThere are exhaust risers on every marine inboard engine. The exhaust riser has two purposes: first, it prevents water from backing up into the engine through the exhaust pipe; second, it introduces cooling water into the system of exhaust exit piping. Before making a severe turn in the direction of the boat's back, the risers rise six to eight inches above the manifold. The majority of clogging issues happen at this acute angle.\u003c\/p\u003e\n\u003cp\u003eIf you discover that your boat has extensions, you cannot remove them since they increase the height above the waterline, preventing water from flowing back into your engine. If risers are required, the hull design and engine installation will be affected.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor long-term durability, made of materials with great strength.\u003c\/li\u003e\n\u003cli\u003eEndures hardest circumstances.\u003c\/li\u003e\n\u003cli\u003eProves giving unmatched resistance to rust and corrosion.\u003c\/li\u003e\n\u003cli\u003eEnsuring these extensions survive by offering exceptional strength and corrosion resistance!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpecifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: 3853621\u003c\/li\u003e\n\u003cli\u003eWeight: 4.73 LBS\u003c\/li\u003e\n\u003cli\u003eDiagram Reference Number: 1\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number (MPN): 3853621\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cbr\u003e\nVolvo Penta Exploded view \/ schematic Exhaust Riser, 3'' Extension\n\u003cspan itemprop=\"mpn\" hidden\u003e3853621\u003c\/span\u003e","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53764140466357,"sku":"QBP878023","price":274.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1117432_qbp878023jpg.jpg?v=1794595152","url":"https:\/\/www.qualityboatparts.com\/products\/qbp878023","provider":"Quality Boat Parts","version":"1.0","type":"link"}
