{"product_id":"qbp599547","title":"Jabsco Fish Box Evacuation Pump, 5 GPM, Diaphragm, 1.5 in Ports","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Jabsco 50900 is a fish box evacuation pump for moving water, meltwater, bait residue, ice particles, and fish scales out of fish boxes and similar onboard compartments. It uses a single diaphragm pump design with 1-1\/2 in. (38 mm) hose connections and a flow rate of up to 5 US gpm (19 lpm), giving anglers a practical way to clear a fish box without relying on gravity drainage alone.\u003c\/p\u003e\u003cp\u003eThis pump range is available in 12V and 24V DC versions, so it can be matched to the boat’s electrical system. It is self-priming to 9.5 ft. (3 m), supports dry running, and does not require a filter, which is useful in a fish box where small debris is part of normal use.\u003c\/p\u003e\u003cp\u003eThe pump suits center consoles, sportfish boats, and cruising boats with fish boxes, fish wells, or cooler-style storage that needs active evacuation after fishing or dockside cleanup. Multi-positional ports and a 360 degree rotatable head help with tight installations where hose routing and service access matter.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eSingle diaphragm pump made for fish box evacuation, including water mixed with bait residue, ice particles, and fish scales.\u003c\/li\u003e\n\u003cli\u003eFlow rate up to 5 US gpm (19 lpm) for clearing fish boxes and similar onboard compartments.\u003c\/li\u003e\n\u003cli\u003eSelf-priming to 9.5 ft.

This version fits boats with a 12V house or pump circuit and keeps the same fish box evacuation layout as the range.\u003c\/li\u003e\n\u003cli\u003e50900-1100: 24V DC. This version fits vessels wired around a 24V DC system, often used on larger boats with higher-capacity electrical installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eUse 1-1\/2 in. (38 mm) inside diameter, non-collapsible marine waste hose on the suction side so the hose does not flatten when the pump is pulling from the box. The pump can be mounted in more than one orientation, but when mounted vertically, the motor should sit above the pump head.\u003c\/p\u003e\u003cp\u003eRubber grommets help absorb vibration, which is useful when the pump is installed under a deck, inside a locker, or near occupied cockpit areas. For dependable service access, leave room around the pump head and hose fittings so the installation can be inspected, rinsed, and maintained after use.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis pump is a good match for boats where the fish box sits below or partly below the waterline, or where the drain path cannot rely on gravity alone. It also works well for fish boxes that double as coolers, where water, melted ice, and small debris collect at the end of the day.\u003c\/p\u003e\u003cp\u003eFor saltwater fishing boats, the main buying points are the debris-tolerant diaphragm layout, the 1-1\/2 in. hose size, and the ability to place the pump where the plumbing run makes sense instead of only at the lowest point of the compartment.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"12V","offer_id":52581966282933,"sku":"QBP599547-V1","price":493.99,"currency_code":"USD","in_stock":true},{"title":"24V","offer_id":52581966315701,"sku":"QBP599547-V2","price":672.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334448_qbp599547.webp?v=1780201862","url":"https:\/\/www.qualityboatparts.com\/products\/qbp599547","provider":"Quality Boat Parts","version":"1.0","type":"link"}
