I got the dreaded call from the marina last spring, my boat was taking on water. Turns out the old float switch had stuck without me knowing. Since I put in BilgeSentinel, I haven't gotten that call again.

Rapid 750 GPH Water Flow
Moves up to 750 gallons per hour with nearly 10 feet of vertical lift, clearing your bilge before rising water can cause damage.

Marine-Grade Corrosion Resistance
ABS747 housing and a stainless steel shaft shrug off saltwater, corrosion, and years of hard use.
Built To Keep Weeds And Debris Out
A built-in filter and anti-fouling impeller stop weeds, string, and hair before they can jam your pump, so you spend less time on maintenance.

BilgeSentinel moves up to 750 gallons per hour with nearly 10 feet of vertical lift, enough for most small to mid-size boats. Serious boaters often run a second pump as backup regardless of brand, simply for redundancy in worst-case flooding.
You can install it yourself. Everything is clearly labeled, the mounting hardware is included, and most boat owners have it wired in and running in well under an hour, no electrician required.

A few short cycles after rain or heavy chop is normal. If it starts running constantly or far more than usual, that usually means water is getting in faster than expected, and it's worth checking your bilge.
Yes. BilgeSentinel is a submersible pump built to run fully underwater in your bilge. It's designed for exactly the flooded conditions it exists to pump out, not just light splashing.
