Sea-Dog Bilge Pump Water Alarm Panel 423033-1, 12 Volt Audible and Visual Bilge Alarm

The Sea-Dog Bilge Pump Water Alarm Panel (423033-1) gives boaters both an audible and visual warning that water in the bilge has risen above the bilge pump float switch level, so a rising water problem is caught before it becomes a serious one. The panel is constructed of injection molded ABS for corrosion resistance in a marine environment and is rated for 12 volt systems with a 15 amp fuse. It installs with four RH fasteners (not included), making it a straightforward add to any helm or panel layout.

This alarm panel is a standalone warning device and does not include a bilge pump switch. For a complete setup that combines pump control with the alarm function, it is designed to be used alongside a Sea-Dog Bilge Pump Switch Panel (423030, 423040, or 423046). Buyers who want the alarm and switch combined in one unit should instead look at the Sea-Dog Bilge Pump Water Alarm Panel with Switch (423035-1).
