Only the best bilge pumps can help you to safely manage such situations. Simply put, these pumps come in handy when you need to send water back out – quickly.

Unfortunately, not all pumps available out there can be trusted with such crucial tasks. And that’s why we created this article to educate our readers on the dos and don’ts of choosing a bilge pump as well as offer our 7 top picks.

How to Choose a Bilge Pumps [Buyer’s Guide]

Bilge PumpsThese pumps are made for the sole purpose of draining water from a specified place or shipping vessel. However, their features and mode of performance may vary.

The following factors explain in details on how to gauge the ideal bilge pump for your needs.

  • Type of Boat/Kayak

The type of boat determines where the boat can be sailed on. Sailing through rougher seas means you will be dealing with more bilge water while navigating through calm water bodies leads to the collection of less bilge water.

Luckily bilge pumps are available in different categories to suit all these mentioned needs.

  • Size of Boat/Kayak

A larger vessel would require a bigger pumping device than a smaller one. It’s that simple. And as we’ll see later, in some cases, you may need more than 1 pump depending on the surface area you intend to cover.

  • Number of Boat Compartments

How many compartments does your boat have? A boat with many compartments will need a more efficient pump and sometimes multiple pumps to remove the water out.

On the other side, a boat with fewer compartments may work with only one bilge pump hence easy to stabilize.

  • Whether Electric or Manual

Manual water pumps work great on kayaks, while larger boats require automatic bilge pumps to deal with the more amount of water.

This is because larger boats are usually motor powered and will have a place for a switch to power the bilge.

  • Pump Capacity

This goes hand in hand with the boat’s size. For example, you can’t buy a small-sized pump for a larger boat.

Powerboats measuring about 18 feet will do just well with pumps of a capacity of 300-500 GPH (Gallons Per Hour).

However, those above 23 feet will demand a pump output of (450-700) GPH.

The figures go upwards as the size of the boat increases.
