When you are out on the open water, the last thing you want to worry about is your vessel taking on water. Whether it is a slow leak, heavy rain, or a splash over the gunwale, unwanted water in your bilge is a reality of boating life. It is not just an inconvenience; it can be a serious safety hazard and cause significant damage to your boat’s structural integrity and electrical systems.
This is where a high-quality bilge pump becomes your most valuable crew member. Acting as the heart of your boat’s drainage system, these devices are designed to remove water effectively and keep your vessel buoyant and safe.

The Unsung Hero of Marine Safety
Many new boat owners overlook the importance of the humble bilge pump until they find themselves ankle-deep in water. The bilge is the lowest point on a boat’s inner hull, where water naturally collects. This water can enter through various means, including leaks in the hull, through the propeller shaft packing gland, or simply from washing down the deck.
If left unchecked, this water can destabilise the boat, cause fuel inefficiency due to added weight, and eventually lead to sinking.
Who Needs a Bilge Pump?
The short answer is: every boat owner.
Whether you are skippering a massive yacht or a small wooden fishing boat, you need a way to expel water. For smaller wooden boats or dinghies, a manual bilge pump might be sufficient to do the job. However, for larger fibreglass vessels and cruisers, electric automatic bilge pumps are the preferred standard. They offer the peace of mind that comes with knowing the pump will activate even if you aren’t there to flip a switch.
How Does a Bilge Pump Work?
Understanding the mechanics of these devices can help you make an informed decision when browsing for a boat bilge pump for sale. While there are different types of pumps, centrifugal pumps are the most common in the marine industry.
Here is a step-by-step breakdown of the internal workings of a standard bilge pump:
-
Entry: The liquid enters the pump through an opening located at the centre of the impeller, known as the eye of the impeller.
-
Flow: The water then flows radially out to the impeller’s vanes.
-
Velocity Increase: Due to the rapid rotation of the impeller, the liquid’s velocity increases significantly.
-
Conversion: This high-velocity liquid enters the volute casing or diffuser. Here, the kinetic energy (speed) is converted into pressure.
-
Discharge: Finally, the pressurised liquid is forced out through the pump discharge outlet and expelled from the boat via a hose.
This simple yet effective process allows modern pumps to move incredible amounts of water ranging from 360 gallons per hour (GPH) to over 4000 GPH in a short amount of time.
Choosing the Right Pump for Your Vessel
Selecting the correct pump involves more than just picking the cheapest option. You must consider the size of your boat and the potential volume of water ingress.
Capacity Matters
Larger crafts naturally require larger bilge pumps to handle greater quantities of water. A general rule of thumb is to look at your craft’s manufacturer’s recommendations regarding bilge pumps. However, many marine experts, including our team at Boat Hut, often recommend purchasing a bilge pump with a greater capacity than the minimum suggested specifications. In an emergency, you will never regret having too much pumping power, but you will certainly regret having too little.
Manual vs. Automatic
-
Manual Pumps: These require the user to physically turn the pump on via a switch at the helm. They are effective but require monitoring.
-
Automatic Pumps: These come equipped with a float switch (either internal or external). When the water level in the bilge rises to a certain point, the switch activates the pump automatically. This is essential for boats left moored in the water for long periods.
Top Brands
Quality matters when it comes to safety equipment. We source our stock from genuine manufacturers to ensure efficient operation. Brands like Rule, SPX Johnson, Whale, and Attwood are industry leaders known for their reliability and durability in harsh marine environments.
Installation and Maintenance Tips
Once you have selected your pump, proper installation and maintenance are key to ensuring it works when you need it most.
Installation: Ensure the discharge hose is smooth (not corrugated) on the inside to maximise flow rate. Keep the hose run as short and straight as possible. If your pump doesn’t have a built-in check valve, ensure the discharge outlet is high enough above the water line to prevent back-siphoning.
Maintenance: The bilge is often a dirty place, collecting oil, hair, sand, and fishing debris. This debris can easily clog the intake of your pump. Regularly inspect the pump’s strainer and clear away any gunk. It is also wise to test the float switch periodically to ensure it hasn’t become stuck in the “off” or “on” position.
