The best bilge pump can be your lifesaver and the secret hero under your seat while sailing the sea. If you have a reliable, well-built, and quiet unit at hand, this unit will provide great value if water ever breaks into your vessel.
There are numerous models to choose from – automatic, manual, lightweight, heavy-duty, etc. Currents are unpredictable so it’s better to have one pump in operation and another, spare one. You can find both in our reviews. We also created a buying guide to make you more familiar with the bilge pump operation, installation, and most important features of this unit so you can ensure you are fully safe when on water.
Benefits Of Bilge Pumps
If you have a high-quality, reliable bilge pump, this unit can provide you with a couple of benefits, including the following ones:
You can store your bilge pump anywhere you want. You can move it around your vessel or store it somewhere else in your home, garage, or car when you are not using it. Most units in this category are lightweight but you will come across heavy-duty ones as well. Although categorized as heavy-duty, these units are relatively easy to move as well.
A functional bilge pump can get you out of a dangerous situation if water ever gets into the bottom of your vessel. If you have a recreational vehicle such as a kayak or canoe, water can get inside quite easily but if you have a small yacht – you already know you are in trouble when there is water in the underwater part of your boat.
Either way, a bilge pump provides a higher level of safety and makes you feel more confident about being far away from the coast.
Bilge pumps are very practical, helpful, and space-saving units. Storing one on your boat won’t take up much space as most bilge pumps are convenient and rather small so you can tuck your away at the bottom of your boat, just like you would do with your boat anchor and anchor rope.
If you are thinking about raw upfront costs of getting a bilge pump, do not fret. These units are affordable, especially when taking into account the value they provide. You can find a good unit for a relatively low price but don’t be afraid to spend a little bit of extra on a bilge pump if you have a larger boat.

What Are Bilge Pumps and How Do They Work?
One of the most important elements on your boat, a bilge pump, is a piece of marine equipment that removes water coming into your ship. It is usually located in the underwater part of a vessel. This pump can handle fuel, mud, and other particles found in the water. Most importantly – a bilge pump can save your life if you have a reliable unit.
Bilge pumps are activated by either electricity or hand movements to collect water. It sucks water in an then releases it from your vessel through a discharge point.
If you want to stay afloat, no matter the water you are on (salt or freshwater, sea or a lake), a bilge pump is an essential unit. However, we highly recommend having a spare pump near at hand in case anything goes wrong.
Types Of Bilge Pumps
Not all bilge pumps are the same. It all depends on the size and draining capacity, as these two factors are taken into account when choosing between one of the following two types.
1. Diaphragm Electrical Pump
This is a typical, standard type of a bilge pump and it sucks water out. It acts like a vacuum and it pushes the water up towards the discharge point. Self-priming, this type is not so portable and requires more maintenance but causes low to no damage.
2. Centrifugal Electrical Pump
This type of bilge pump operates as a turbine. It uses kinetic energy and features a high draining capacity. More affordable, easier to maintain, and store – the centrifugal electrical pump is a slightly more popular model that the diaphragm electrical pump, although both types have its cons as well.
Bilge Pump Buying Guide
Here, you will find the most important features of any bilge pump. To ensure the best return of value on this purchase, make sure to find a unit that ticks all of the following characteristics.
Probably the most significant feature of a bilge pump – its draining capacity is expressed in gallons per hour (GPH). It is essential to check on this output beforehand making a final decision. You can find pumps with 500, 750, 1100, or 2000 GPH.
A bilge pump with lower output capacity won’t be able to deal with tough currents and fast water inflow. Choosing the best pump will depend on the size and type of your vehicle. You need to find a unit that will pump water out fast enough so your boat doesn’t sink.
The size of a bilge pump is a quite important feature into account as well. If you have a small vessel, a bulky unit will take a lot of space and you won’t have any room left for other important pieces of marine equipment.
On the other hand, the size of a pump sometimes defines its output. If you have a yacht or a bigger boat, it would be best to find a pump of appropriate size and the one that has a solid draining capacity. This will ensure your safety in case water gets into your boat’s underwater part.
We have already discussed 2 types of bilge pumps. If you have a larger boat, we would highly recommend a centrifugal pump and diaphragm pump for boats where you need to push the water upwards to the discharge point.
4. Ease Of Installation
If you want to ensure the long life of a bilge pump, you should clean it at least a couple of times during one season. Dirt and large particles can clog your pump and hinder its operation. No matter how large your pump or the pump’s hose is, you should maintain it frequently. For the reason you will have to assemble and disassemble the pump numerous times, it is important to have one that’s easy to mount as well.
The build of a bilge pump affects its lifespan too. If it is strong and well-made, the unit will be resistant to weather, fast-moving water, sizeable leaks, and other impacts.
The best material used for making bilge pumps is ABS plastic. It can stand heavy use and won’t break under the influence of strong currents. However, other parts such as gears and shafts should be well-made as well. Stainless steel is a top-quality material that ensures the longevity of a bilge pump but it is resistant to corrosion too, which might be important if you spend most of your days on the sea.
6. Noise Level
Not all bilge pump descriptions involve noise level rating in decibels, but it would be great if you could find the unit that does. A bilge pump should operate in a silent manner and, if possible, without vibrations. The quieter the pump – the better, as it won’t annoy you or drive fish away.
Some models come with built-in equipped water sensors that activate the pump only when there is some water in your boat. This way, you can save u some energy and ensure the long life of your pump.
7. Boat Type and Size
In order to find a pump that is most suitable for the type of your boat and its size, make sure to pay attention to this section. We are going to categorize different boat types and sizes and suggest the most important features of the most suitable unit.
If you have a smaller boat, such as an outboard-powered skiff or a daysailer, then you have a narrow and more compact bilge. This means you should find an appropriate – smaller bilge pump. It would be best to find a versatile unit that can be installed vertically and horizontally.
Next, if you are a ski boat or runabout owner, that means your vessel is capable of handling more water itself. A boat pump will come suitable in emergency situations but still – make sure to find a heavy-duty one that boasts a higher capacity.
With racing sailboats, you also need a pump with a higher draining capacity but a lightweight unit. A heavy-duty pump would hinder your speed and make you fall behind other boats.
Yet, as not all racing sailboats are the same, if you have an offshore racing sailboat, a powerful and sturdy pump is a must. You need a unit that can be installed at almost any angle and pump enough water to the discharge point to keep you afloat.
If you spend most of your time on your offshore or coastal boat, you need a reliable pump that is not too bulky but the one that features a high draining rating. This will ensure you some extra time to call for help through your VHF marine radio.
You can choose between electric and manual bilge pumps. We can’t claim one type is better than another as both can provide more safety on the water. Yet, electric bilge pumps are slightly more efficient and can pump more water in a shorter time.
On the other hand, you might not need an electric pump for smaller vessels such as kayaks. In this case, a manual bilge pump will do the job without much effort. It will help you get water, mud, and other particles from your vessel.
Still, beware of the fact electric pump will drain power from your motor while manual-operated pumps require more effort than electric units.
9. Pump Switches
Some pump switches are designed to turn bilge pumps into operation automatically. One of these switches is the integral automatic switch built-in more high-end bilge pumps. Once the switch detects water in your boat, it will power the pump to start draining water out.
However, most units on the market come without a built-in float switch so you would have to buy and install one separately. This way, you can transform your bilge pump into an electric unit.
Again, this might be a better option for large boats and yachts where you can’t keep an eye on the water level. With kayaks and canoes, you can have a clear insight into the upcoming water level and turn the pump manually.
Although it would be best for you to throw out some other unnecessary objects from your boat for the sake of a bilge pump, we guess some of you still care about the free space on your vessels. In our reviews, you can find a couple of easy-to-store units that can give you that extra room for other things you might want to have near at hand when sailing.
How To Install Bilge Pumps?
If you have never installed a bilge pump on your boat, the owner’s manual might be the best thing to have near at hand when mounting the unit. Here, we will provide a couple more installation tips that will make this process easier for you.
Check on the electrical connection. Improperly attached bilge pump will be useless if water enters your boat. Using a crumpled hose will, highly likely, cause you headaches and endanger your safety. Use a smooth hose through which water can flow easily.
In case you are unsure about the process, call a technician and the guy will install everything the right way.
Here is a step-by-step guide on how to install a bilge pump.
- Make sure your discharge hole is above the waterline.
- Find a skin fitting that’s appropriate for the size of your discharge hose.
- Your bilge pump should be running straight and short so place it in a suitable position.
- Drill a hole through which the skin fitting will go. Make the hole fit and snug.
- Connect the skin fitting and the hose to your bilge pump and tighten connections with hose clamps.
- You will need wire – two runs for manual pumps to connect the pump to the bilge.
- If your pump comes with a float switch, find an appropriate size cable and use connectors and heat shrink connect positive and negative wiring.
- Use a ring connector for the negative and a blade cable for the positive cable to complete the circuit.
- Double-check whether the wiring, connections, attachment and the circuit are secure.
Maintenance & Safety Tips For Bilge Pumps
Maintaining your bilge pump is essential for your safety in critical situations. If you want to prepare yourself as much as it is possible, make sure to follow the listed steps before setting sail.
- Take into account the essential features of a bilge pump – mostly the ones that have to do with the size and type of your boat.
- In case your pump breaks down in the middle of the sea, always have a spare one to help you out.
- Place the pump in a place from which it can pump water out of your boat most efficiently.
- If you are not sure about your pump’s operation, call a technician.
- Clean your bilge pump after each sail. Large particles stuck in the discharge hose can cause a clog and prevent the pump from operating efficiently.
FAQ About Bilge Pumps
1. How High Can a Bilge Pump Lift Water?
A bilge with rated at 500, 750, and 1100 GPH can pump water up to 10 feet, and those rated at 2000 GPH can push water to 18 feet.
2. Do I Need More Than One Bilge Pumps?
As listed, different bilge pumps are rated at different power outputs. A bilge pump can save you from an emergency but – what if it fails you when on the water? Even if it doesn’t, rough seas and torrential rains might put too much pressure on your pump.
In case your pump doesn’t boast a high draining capacity, it will be quite troublesome to get out of a dangerous situation. To ensure your peace of mind on the water, we highly recommend having at least one spare pump. Even a smaller-capacity pump can be of great help in case of an emergency.
Also, if you have an electric pump, it would be smart to have a manual one as well.
3. Why Can a Bilge Pump Fail and What Happens Next?
Any pump can fail, including a bilge pump. Anything putting restrictions on your pump can make it stop working – mostly large particles, dirt, and debris stuck in the discharge hose. Any particles found in the water can hinder the operation of a pump.
Sometimes, the water can get back into the unit if siphoning is bad. If wiring is not installed properly, this can be another reason for pump failure. Salt is one of the major irritants to wiring, while the same applies to fuel.
If a bilge pump fails, it can cause collecting more water in the underwater part of your boat. If the water is not coming out of the vessel, you wouldn’t be able to stay afloat. That’s exactly why you should have two bilge pumps on your boat – to prevent your boat from sinking.
Now you know the best bilge pump can protect you if you ever get involved in a dangerous situation on the water – whether it be heavy rain or strong currents. If you want to prevent sinking of your boat, a bilge pump can help you stay afloat or give you some extra time to call for help.
