Johnson Pump Ultima Bilge 1250 GPH 1-1/8" & 1-1/4" Hose - 32-47261-002

Johnson Pump Ultima Bilge 1250 GPH w/ Integrated Switch (32-47261-002)

The Johnson Pump 32-47261-002 represents the highest capacity in the Ultima series of integrated automatic bilge pumps. Delivering a powerful 1250 GPH, this unit is designed for larger vessels that require high-volume water removal and the utmost reliability of solid-state electronics. By combining the pump and sensor into a single, compact housing, it eliminates the need for a separate mechanical float switch.

Solid-State "Mirus" Reliability

The standout feature of the Ultima Bilge is its patented Mirus field-effect detector cells. These sensors are completely sealed and have no moving parts to jam with hair or debris—the leading cause of bilge pump failure. The sensors are "smart," meaning they are designed to detect water only; they will not accidentally trigger the pump if they encounter a layer of engine oil or fuel, preventing unwanted discharge of pollutants.

Key Features:

• High-Capacity Output: Moves 1250 GPH (79 L/min), providing rapid dewatering for mid-to-large sized cruisers and offshore boats.

• Integrated Automatic Sensing: Automatically turns on when water levels reach 2" (50mm) and shuts off at 3/4" (20mm).

• Dual Dura-Port Fittings: Includes both 1-1/8" and 1-1/4" high-impact discharge ports. The Dura-Port design resists stress cracking and makes hose installation easier.

• Removable Cartridge: The motor unit can be unclipped from the strainer base for easy maintenance or replacement without disturbing your plumbing or mounting screws.

• Low Vibration & Quiet: Engineered for smooth, silent operation to minimize noise in the cabin.

• Ignition Protected: Meets USCG, ABYC, and ISO 8846 standards for safe installation in gasoline engine compartments.

• Compact Footprint: Despite its high flow rate, the unified design saves valuable space in the deepest part of the bilge.

Why Choose the Ultima Bilge 1250?

The 32-47261-002 is the premium choice for boaters who want "set-and-forget" security. The 1250 GPH motor provides an extra margin of safety for offshore use, while the electronic switch eliminates the mechanical failures common in traditional setups. It is an ideal "drop-in" upgrade for older, less efficient 500 or 750 GPH pumps.

Installation Pro-Tip:

When wiring the Ultima Bilge, ensure all wire connections are made above the maximum expected bilge water level using heat-shrink butt connectors. This protects the wires from "wicking" moisture into the pump motor, which is the most common cause of premature pump failure.
