JOHNSON SPX L1600 Bilge Pump, 6000 L/h, 12V 98000132

Overview

The JOHNSON SPX L1600 12 V bilge pump ensures rapid removal of water that accumulates in the bilge of a motorboat or sailboat. With a capacity of 6,000 L/h, it is well-suited for medium-sized vessels or professional applications where the volume of water to be pumped requires a high submersible flow rate.

Technical Specifications

Recommended operating conditions

Install the pump at the lowest point of the bilge, with the outlet routed upward to a through-hull fitting located above the waterline. Ensure that the wiring is protected by a fuse and that the wire gauge is appropriate for the run length to minimize voltage drops.

Technical benefits

• Flow rate of 100 L/min → rapid drainage in the event of moderate water ingress or a clogged hull
• L1600 model from the professional line → designed for repeated use without any loss of performance
• 28 mm outlet → directly compatible with standard hoses and through-hull fittings of this size

Usage and Maintenance Tips

• Clean the intake strainer periodically to prevent clogging by debris and hair
• Check the tightness of the hose connection and the condition of the hose clamp before each launch
• Test the unit in dry running mode for only a few seconds; the motor is cooled by the pumped water

Frequently Asked Questions

Is this pump suitable for use in seawater?

Yes, JOHNSON SPX bilge pumps are designed to operate in both saltwater and freshwater. Their construction is engineered to withstand continuous exposure to a marine environment. It is still recommended to rinse the bilge and the pump with freshwater after a prolonged period of winter storage to prevent deposits.

Is a separate switch required for this pump?

This model does not come with a built-in automatic contactor. For unattended operation, a float switch or an Auto/Off/Manu control panel connected between the battery and the pump must be installed. This configuration allows the pump to start automatically as soon as the water level rises in the bilge.

What cable gauge should be used for the electrical connection?

The cable gauge depends on the length of the run between the battery and the pump. For distances under 3 meters, a 2.5 mm² cable is generally sufficient. For longer distances, you should use a 4 mm² cable or larger to minimize voltage drops that would reduce the pump’s actual flow rate.
