A Bilge Pump is essence is a water pump used to remove bilge water and is usually located below the waterline. It uses a desired pressure to direct water through an intake valve and then through the outlet barge where it leaves the boat.
The best Bilge pump is the Shoreline Marine Pump as its very compact yet packs a lot of power with a GPH rating of 600, which considering its low cost is very impressive.
There are a range of bilge pumps from electric, manual, automatic/manual electric, priming and an installed bilge pump. Every bilge pump will have a GPH rating that determines how many gallons it can remove per hour.

Bilge Pump Buying Guide
The water pump used in the bilge save your boat from sinking, which can be at the dock or miles out to sea. It is an essential piece of boating equipment with multiple factors to consider.
Different Types of Bilge Pumps
There are 2 different groups of pumps that are used within the boating scenarios, these include:
- Electric or Manual. Pumps that run from the boats electric with a switch of a button or manual that require use of a hand pump to remove the water.
- Electric Automatic. Automatic bilge pumps sense when the water is at a level where it needs to be removed and then activates the pump.
Choosing between the two is up to the personal preference of the boat owner. Many automatic pumps will have a manual override option with a float switch or you can either wire one in yourself.
Gallons Per Hour Pumping Capacity
With technological advances, bilge pumps have become smaller and more powerful with much higher GPH ratings. GPH stands for Gallons Per Hour, with the rating being the number of gallons of water it can remove from the bilge.
The pumping capacity of your pump matters and if you have a boat that is over 16 foot, you should be investing in a powerful pump or multiple pumps to combine the GPH.
Just because a bilge pump states it may remove 1000 gallons of water per hour, do not stand by this. It is more likely to remove half of that because there are other vairables such as vertical distance, voltage conditions and other scenarios.
If you ask boat owners for large vessels, you will more than likely be told they have two bilge pumps to ensure water is removed as quickly as possible if it reaches a certain level.
For small inflatable boats, a bilge pump is not necessarily required. However, if you have an outboard boat engine with a inflatable rib, you will require one.
