Best Kayak Bilge Pump

A bilge pump is a must-have if you are an avid kayaker, regardless of whether you usually paddle on lakes, rivers, or the open water of the sea. To buy the most suitable bilge pump for your kayak, however, you have to know a little bit about the different buying considerations and specifications for this type of pump.

In this buyers’ guide, we will be taking an extensive look at the workings of a bilge pump. We will also review some of the best kayak bilge pumps available for purchase.

Purpose of a Bilge Pump

The bilge is the lowest compartment of a watercraft. In most cases, the bilge is located below the water level. While kayaking, water may accumulate in the bilge because of waves, capsizing, or leaks.

If you have water in the bilge of your kayak, it can be quite uncomfortable and, depending on the amount of water, even dangerous. Water accumulation in the bilge can also be inconvenient, as you will have to interrupt your paddling session and head to the shore to get rid of the water.

Having a bilge pump on board solves all of these problems. Pumping the water out is the only way to clear the bilge and continue kayaking. If you typically paddle in circumstances where water will likely accumulate in your kayak’s bilge is likely, it may be worth investing in a pump.

Power Source

When it comes to power, you have two options: manual bilge pumps and automatic bilge pumps.

Manual Bilge Pumps

Manual bilge pipes are ideal for smaller kayaks as they are lightweight and compact. These pumps are also more affordable than automatic bilge pumps.

They require you to lift the pump handle up and down to project water out of a spout and out of your kayak. One of the drawbacks of a manual pump is that clearing a lot of unwanted water from your kayak’s bilge can take a long time, as manual pumps typically don’t have a high flow rate.

If you use a manual bilge pump, you also have to stop paddling or fishing and concentrate on clearing the water from your kayak.

Automatic Bilge Pumps

If you typically experience a lot of water accumulation in your kayak’s bilge, an automatic bilge pump may be the better option, as you can switch the pump on and continue with your kayaking activities.

An automatic bilge pump uses a battery-powered motor to pump water from your kayak. The downside of an automatic bilge pump is that it takes some time and effort to install. Automatic pumps also take up more space than manual pumps, and they don’t offer the same portability.

Size and Flow Rate

Bigger bilge pumps can typically remove more water from your kayak’s bilge per minute. If you have a single kayak, a bilge pump with a size of 17.5” to 20” that removes 8 gallons per minute (GPM) will be sufficient for occasionally eliminating water from the bottom of your kayak.

A manual pump requires, on average, eight strokes to remove one gallon of water. If you have a two-person kayak, you need a bilge pump with a larger capacity – preferably 20” or longer. For casual solo kayakers, a small and portable manual pump of 8 GPM will be more than sufficient.

A factor to consider when choosing the size of your kayak water pump is storage. It may be tempting to buy a powerful and bulky bilge pump to ensure that you never have to deal with water at your feet, but pumps that are larger than necessary can take up a lot of valuable space that you may prefer to use for fishing or safety gear.


Before you choose a pump, take some time to consider the layout of your kayak cockpit and how you will go about installing your bilge pump. In most cases, it is not as simple as throwing your manual pump somewhere near your feet and hoping that you will be able to reach it when the need arises. You also don’t want your manual pump to fall into the water accidentally. Attaching a cord or clip to your kayak that connects to your manual pump is often the safest and most convenient solution.

If you have an automatic bilge pump, it will require a little more effort to ensure that you install the pump so that its switch is within reach and that the wiring is out of your way. Fortunately, most automatic pumps come with thorough instructions to help with proper installation.


Now that you know a bit more about the types of pumps, their flow rates, and installation requirements, let’s take a look at some of the best kayak bilge pumps for avid kayakers.
