Maretron BHW100 Bilge High Water Detector

The Maretron BHW100 Bilge High Water Detector is an essential early-warning system for any boat owner who takes bilge management seriously. After years on the water, any experienced skipper knows that undetected bilge accumulation can escalate from a minor inconvenience to a catastrophic engine threat in hours. This sensor works in conjunction with the Maretron SIM100 Switch Indicator Module to continuously monitor your bilge water level and alert you the moment water rises beyond safe operating thresholds, giving you the critical advance notice needed to address pump failures, hull breaches, or cooling system leaks before they compromise your vessel.

This compact detector utilizes proven float-switch technology housed in a rugged, corrosion-resistant body designed to withstand the harsh marine environment. Weighing just 0.1 pounds and measuring 7 x 1 x 7 inches, the BHW100 installs easily in tight bilge compartments without taking up valuable space or impeding pump operation. The sensor's simple but effective design requires no calibration and integrates seamlessly with Maretron's networked marine electronics systems, providing real-time bilge status data directly to your helm display or mobile monitoring platform. Its reliability stems from decades of marine automation engineering—the same technology trusted on commercial fishing vessels and offshore cruisers.

Cruising anglers, liveaboard operators, and anyone regularly running extended offshore missions will find the BHW100 indispensable for unattended monitoring during overnight passages or when you're focused on fishing rather than engine room checks. Installation pairs the detector with the SIM100 module to create a complete bilge monitoring circuit that fits into your existing Maretron N2K network or standalone marine system. Whether your boat features a single-engine cruiser setup or complex multi-engine configurations, this detector provides the same dependable performance—affordable insurance against the one maintenance oversight that could cost thousands in water damage or total engine loss.
