{"product_id":"qbp961385","title":"Attwood Marine Tsunami MK2 T500 Manual Bilge Pump Kit, 500 GPH, 12V, 3\/4 in Hose Outlet","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Attwood Marine 5614-7 is a 12V non-automatic bilge pump kit built around the Tsunami Mk2 T500 pump. It is rated for 500 GPH and comes packaged as a complete 3\/4 in I.D. hose installation set, so you are not piecing together the hose, thru-hull fitting, switch, wiring, and small hardware separately.\u003c\/p\u003e\u003cp\u003eThis is the right kind of setup when you want a manually switched electric bilge pump rather than an automatic pump with a built-in float or sensor. The Tsunami Mk2 pump uses an X-Air impeller that clears trapped air from the pump and discharge line, which helps in installations where hose routing or mounting position can leave air pockets behind.\u003c\/p\u003e\u003cp\u003eThe pump itself is IP68 rated, uses a 29 in lead, and can pump down to a 10 mm water level. The T500 pump accepts 3\/4 in and 1 in barbed outlet connections, while this kit is packaged around a 3\/4 in discharge run.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e12V Tsunami Mk2 T500 bilge pump rated at 500 GPH for a manually switched bilge circuit.\u003c\/li\u003e\n\u003cli\u003eX-Air impeller helps clear trapped air from the pump and pipework, which reduces the chance of an airlock stopping flow.\u003c\/li\u003e\n\u003cli\u003eInstallation kit is arranged for a 3\/4 in I.D. hose run and includes the discharge hose, matching thru-hull fitting, clamps, switch, wire, and fuse holder.\u003c\/li\u003e\n\u003cli\u003eIP68 pump construction with an SS316 motor shaft and nitrile seals for bilge spaces that stay wet.\u003c\/li\u003e\n\u003cli\u003e29 in pump lead, plus 20 ft of 16-gauge wire in the kit, gives more room when the switch panel sits away from the bilge.\u003c\/li\u003e\n\u003cli\u003eMinimum water level of 10 mm helps the pump pull the bilge down lower before water is left behind.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThis kit is intended for a 12V DC system and a manually controlled pump circuit. The included 2-way on\/off switch gives you a straightforward helm or panel control, but the switch is not external ignition protected, so it should not be installed where that protection is required.\u003c\/p\u003e\u003cp\u003eThe discharge side is built around 3\/4 in hose, with a 5 ft corrugated hose and matching thru-hull fitting included in the box. On boats where the bilge space is tight, the Mk2 layout is easier to work with than older pump designs because service access to the cartridge is simpler and the mounting arrangement is friendlier for retrofit work.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis pump suits boats that use a 12V electrical system and need a compact, manually switched bilge pump in the 500 GPH range. It works well for smaller bilge compartments, secondary pump positions, and general bilge duty where a simple switch-operated setup is preferred over a more complex automatic system.\u003c\/p\u003e\u003cp\u003eIf you are replacing an older pump, the Mk2 range keeps retrofit-friendly mounting options for some earlier Tsunami Mk1 and Johnson L Series layouts. That can reduce drilling and rework when you are updating an existing installation.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eTsunami Mk2 T500 bilge pump\u003c\/li\u003e\n\u003cli\u003e2-way on\/off switch with bezel plate\u003c\/li\u003e\n\u003cli\u003e3\/4 in I.D. x 5 ft corrugated hose\u003c\/li\u003e\n\u003cli\u003eThru-hull fitting for 3\/4 in I.D. hose\u003c\/li\u003e\n\u003cli\u003eTwo Snap-It hose clamps\u003c\/li\u003e\n\u003cli\u003e2-conductor 16-gauge wire, 20 ft long\u003c\/li\u003e\n\u003cli\u003eIn-line fuse holder\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":52023561486517,"sku":"QBP961385","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1329492_qbp961385.jpg?v=1780191881","url":"https:\/\/www.qualityboatparts.com\/products\/qbp961385","provider":"Quality Boat Parts","version":"1.0","type":"link"}
