It uses a cap made from stainless steel at deck level and an integrated vent arrangement inside the fill body.\u003c\/p\u003e\u003cp\u003eThis part is marked for gasoline service and uses a built-in vent path rather than relying on a separate deck vent fitting. For replacement work, the round cap measures 85 mm, with a 54 mm neck cutout and a 20 mm vent cutout. Installation uses four #8 screws.\u003c\/p\u003e\u003cp\u003eThis version belongs to Attwood's international gasoline deck fill range and is not for U.S. or Canada gasoline applications.

If you bump bottom or hit debris, inspect the blades for cracks and keep a spare prop kit onboard so a damaged prop does not end the day early.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003eMGA0476B\u003c\/span\u003e","brand":"MotorGuide","offers":[{"title":"Default Title","offer_id":53721608388789,"sku":"QBP629645","price":46.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1280722_qbp629645.jpg?v=1794119843"},{"product_id":"qbp826359","title":"Attwood Marine Cowl Vent, 3 in Ventilation Hose, Chrome-Plated ZAMAK","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Attwood Marine 1364A1 is a deck-mount cowl vent for standard 3 inch ventilation hose. It can be set up as either an intake or an exhaust, so it works where you need passive airflow through an enclosed space rather than a powered blower.\u003c\/p\u003e\u003cp\u003eThis vent uses a flexible flange attachment that connects to the hose below deck, then accepts the vent head once the base is mounted. The vent body is die-cast ZAMAK with a chrome finish, and the flange is black plastic. For the installation shown in the instructions, the deck opening is 3-1\/2 inches when a nylon wire tie is used as the hose clamp.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFits any standard 3 inch ventilation hose\u003c\/li\u003e\n\u003cli\u003eCan be used for either intake or exhaust airflow\u003c\/li\u003e\n\u003cli\u003eDie-cast ZAMAK vent head with chrome finish\u003c\/li\u003e\n\u003cli\u003eBlack plastic flange attaches the hose below deck\u003c\/li\u003e\n\u003cli\u003eFlexible flange-and-head design allows the vent head to snap onto the mounted base\u003c\/li\u003e\n\u003cli\u003eInstallation uses three #8 countersunk screws and a hose clamp or 15 inch nylon wire tie\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eThis is a straightforward replacement part when your boat already uses a 3 inch vent hose and a deck cowl in this style. The base is used as the drilling template, the hose slides up through the deck cutout and over the flange, and the vent head attaches after the base is fastened down. It is worth checking the deck opening before ordering, since the stated 3-1\/2 inch hole size is tied to the clamp method used during installation.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis vent suits refit work on boats that need passive deck ventilation through a hose-fed run below deck. It makes sense for owners replacing an older cowl vent on a sailboat, runabout, or classic fiberglass boat where the existing hose size and mounting style need to stay the same.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e1364A1\u003c\/span\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":53721615302837,"sku":"QBP826359","price":39.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1322187_qbp826359.webp?v=1794120696"}],"url":"https:\/\/www.qualityboatparts.com\/collections\/cat-engine-systems.oembed","provider":"Quality Boat Parts","version":"1.0","type":"link"}
