If your boat has a hull, there’s a good chance there’s a bilge. The bilge is the lowest part of the boat, so it’s the first place water will seep in if your boat springs a leak. And regardless of the size of your boat, there’s a pretty good chance your bilge has a few inches of water in it, even when your boat is upright on dry land.
Since you’re reading this, there’s a good chance you’ve already discovered this for yourself. If you’ve ever turned on a light in your boat and been greeted by a cloud of water vapor, you know what we’re talking about. And if you’ve ever gone to start up your boat and found that it wouldn’t start, chances are at least part of the reason was water in the bilge.
Bilge pumps are installed to help prevent water from collecting in the bilge, but they can’t do their job if they’re not working properly, or if they’re not installed correctly. To help you find the best boat bilge pumps we’ve rounded up our top picks and

Best Boat Bilge Pumps Buying Guide
Before choosing the best boat bilge pumps you should consider following options:
1. What the Boat Bilge Pump Is Intended to Do: Every boat owner should have a good idea of what the bilge pump is intended to do.
The basic function of a bilge pump is to remove water from the bottom of the boat by sucking it out with a discharge hose and then transporting it to a place where it can be safely discharged.
The discharge may be connected to a discharge opening on the top of the boat, or the discharge may be connected to a discharge pipe that is lowered into the water away from the boat.
Some pumps are self-priming, which means that the pump will draw in water when the discharge is not active. This is a great feature because it prevents the pump from being out of commission if the discharge pipe is accidentally plugged.
Other pumps are designed to operate continuously with a float switch that turns on the pump when water is detected.
2. Size of the Boat Bilge Pump: The size of the boat bilge pump is extremely important. You don’t want a pump that is too small for your application or one that is overpowered for your application.
While it’s possible to have a pump that is too large, it’s much less likely. If the pump is too small, it won’t be able to remove all of the water from the bottom of the boat in a timely manner.
If the pump is oversized, it won’t have the velocity needed to move the water efficiently. It’s important to have a pump that is powerful enough to move the water, but not too powerful because the discharge pipe can become plugged if the pump is too powerful.
The GPM (gallons per minute) flow rate is the way to determine the size of the pump needed. Start by figuring out the area of the bottom of the boat that will be drained.
For example, if the bottom of the boat is 12 square feet, then the area is 12 square feet. Multiply the area by the GPM flow rate to get the gallons per minute that is needed.
For example, if you need a pump that moves 20 GPM, then you need 240 gallons of water removed every minute.
3. Discharge Location: You need to plan for the pump discharge in advance. The discharge can be from the top of the boat or from a pipe that is lowered into the water.
If the discharge is from the top of the boat, then the pump will be exposed to the weather which may cause damage to the pump. If the pump is exposed to the weather, then it’s a good idea to purchase a self-priming pump.
If the discharge is lowered into the water, then the pump will be protected from the weather and it’s not necessary for the pump to be self-priming.
4. Power Source: You may be surprised to learn that there are pumps that can be powered in different ways. There are some pumps that are completely self contained and will run off of the battery on board.
Other pumps are designed to be powered by a water intake from the boat’s engine. There are also some pumps that are powered by an electric motor that is plugged into a standard outlet.
5. Mounting Location: You also need to have a good idea of where the pump will be mounted. If the boat is anchored in open water then the pump will be exposed to the weather so it’s a good idea to purchase a self
