It moves approximately 80 pounds of ballast water every minute at a 9 GPM (34 LPM) flow rate, and its self-priming design lets it be mounted up to 3 feet above the water source. The pump is constructed with a bronze pump head paired with an oil-resistant nitrile impeller, giving it a long service life in continuous marine use. It runs on a nominal 12 VDC supply, draws up to 12A maximum current, and should be protected with a 20A fuse. Plumbing connects via a 1 inch hose barb or 1\/2 inch NPT internal port. Beyond ballast duty, the same bronze-and-nitrile construction makes it suitable for bilge pumping, livewell circulation, draining bait tanks, engine oil changing, and washdown applications. The pump meets USCG 183.410 and ISO 8846 Marine ignition protection standards, making it safe for use in gasoline engine compartments. It is built as a direct functional replacement for the Mastercraft 300249 ballast pump, so it drops into systems designed around that part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
