{"product_id":"johnson-pump-ultima-combo-automatic-bilge-pump-1250-gph-12v","title":"Johnson Pump Ultima Combo Automatic Bilge Pump, 1250 GPH, 12V","description":"\u003cp\u003eThe Johnson Pump Ultima Combo is an automatic submersible bilge pump rated at 1250 gallons per hour, built for boat owners who want reliable, unattended water removal without a mechanical float switch to jam, stick, or corrode over time. Instead of a float arm, the Ultima Combo uses patented Mirus field effect detector cells that create micro-electrical fields to sense disruptions caused by water or other fluids. Because the detector cells are completely sealed, they never make physical contact with water and cannot corrode, giving the switch a longer, more dependable service life than conventional float-activated designs.\u003c\/p\u003e\u003cp\u003eThe pump itself is a compact, all-in-one motor and impeller unit housed in durable thermoplastic, with a stainless steel (SS2343) shaft supported by a lip seal. The motor is water cooled for energy efficiency and long service intervals, and the housing includes a built-in check valve and a molded T-slot mount for a clean, secure installation. The completely sealed switch design also allows the switch to be located remotely from the pump body, giving installers flexibility in tight bilge compartments.\u003c\/p\u003e\u003cp\u003eElectrically, the Ultima Combo runs on a 12 volt system, draws 3 amps, and is rated for a 5 amp fuse. It uses a 1-1\/8 inch discharge connection and is recommended to be wired with 16 gauge wire. This is a universal-fit automatic submersible bilge pump suitable for bilge compartments across a wide range of boats.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 08203-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Bilge Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Automatic Submersible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate:\u003c\/strong\u003e 1250 Gallons Per Hour (GPH)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Draw:\u003c\/strong\u003e 3 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Size:\u003c\/strong\u003e 5 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge Connection:\u003c\/strong\u003e 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Wire Size:\u003c\/strong\u003e 16 gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Seal:\u003c\/strong\u003e Lip Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Material:\u003c\/strong\u003e Stainless Steel (SS2343)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e Thermoplastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow many gallons per hour does the Johnson Pump 08203-00 move?\u003c\/strong\u003e The Johnson Pump Ultima Combo, part number 08203-00, is rated at 1250 gallons per hour.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this bilge pump use a float switch?\u003c\/strong\u003e No. The Ultima Combo (08203-00) does not use a mechanical float switch; it relies on patented Mirus field effect detector cells that sense water electronically without ever contacting it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage and amperage does the Ultima Combo run on?\u003c\/strong\u003e It operates on a 12 volt system and draws 3 amps, with a recommended 5 amp fuse.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Johnson Pump 08203-00 fully automatic?\u003c\/strong\u003e Yes, the Ultima Combo is an automatic submersible bilge pump that activates on its own when it detects water, with no manual switching required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size discharge hose fits this pump?\u003c\/strong\u003e The Ultima Combo has a 1-1\/8 inch discharge connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat wire gauge should be used when installing this pump?\u003c\/strong\u003e Johnson Pump recommends 16 gauge wire for the Ultima Combo (08203-00) installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the housing and shaft made of?\u003c\/strong\u003e The Ultima Combo has a durable thermoplastic housing and a stainless steel (SS2343) shaft supported by a lip seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the switch on this bilge pump be mounted away from the pump?\u003c\/strong\u003e Yes.
