Best Bilge Pumps
The only thing keeping you from giving your beloved boat an unwanted and unexpected burial at sea is a functional bilge pump. Without it, you have no way of taking water that has infiltrated your boat back into the lake where it belongs.
The time is growing near where the lake is slowly, but surely, starting to thaw, and you have probably been itching to pack away your snowmobiles and go get your boat out of storage. Before you drop your boat back into the water, there are a few measures you should take to ensure for an easy and dry transition.
Before you drop that boat (that has been neglected all winter) into the water this summer, you want to make sure that all of the engine components are in good working order. And that includes your bilge pump. A faulty bilge pump is a surefire way to land your boat at the bottom of the lake, and that is no way to start a cool summer.
Fortunately, investing in a new bilge pump is relatively inexpensive, and it really isn’t that difficult to install, even if you have never purchased one before. If you are getting ready to take your boat out of storage, or are buying a used boat where the status of the pump is unknown, it may be a good idea to pick one up just to be safe.

The Criteria We Used To Find The Best Bilge Pumps
Keeping your boat above the water should be your number one goal, because if it doesn’t float, then it isn’t a boat anymore. The investment of a good bilge pump (alongside with proper maintenance in installation) will ensure that you will be able to leave all of your worries at the dock as you set out for a relaxing afternoon of fishing. There are certain things we kept an eye out for when selecting the best products to meet your boating needs.
When selecting the best bilge pumps, we appealed to one caveat: it is better to spend more money once, than a little money over and over again. If we were telling you what kind of steering wheel cover to buy for your new boat, then sure, we would probably lean towards the more inexpensive products. However, bilge pumps are something really important to have on your boat. It would be unwise to utilize a pump that is made from inferior components, or else you will find your beloved boat in the graveyard of other bilge pump-less boats.
If this is something that is going to be sitting on the bottom of your boat and swallowing up all of things that lake and sea water contain, it better be made from some pretty strong stuff (especially if it contains electrical components). A superior unit is typically made from ABS plastic, because it is incredibly durable and waterproof. Definitely make sure that the shell of your bilge pump is made from a strong and durable plastic.
Another thing we kept an eye out for was how well the unit was designed to keep moisture away from the wires. If you can imagine, a bilge pump is exposed to a lot of water, but it also has a few wires that send electrical currents to the motor. So you can imagine how important it is that the wires (and where they affix to the motor) stay dry. Units that have ignition and corrosion protection were considered superior, because they went the extra mile to ensure that the motor stays dry.
If you walk up to the dock and ask any of the fishermen what kind of bilge pump they have in their boat, they are most likely going to tell you that they use Rule pumps. Rule has been making great bilge pumps since 1974 (which is far before many of the other brands on this list). There really isn’t much rivaling competition on the market, but there are some brands that have really started to make a mark for themselves, such as Seaflo, Seasense, and Amarine-made.
Ease of Installation
If you have a smaller boat, or just don’t want to be bothered with wiring, you can always opt for a manual pump. Manual pumps work much like any type of manual pump, and they can only pump out as much water as your arms are able to provide. If you want to take the time to install an electric pump, it really isn’t all that difficult. We tried to select pumps that had an easy installation that didn’t require any unnecessary feats with the wires. We also tried to ensure that each pump came with detailed instructions, so that you could spend less time preparing your boat for the water, and more time alone out on the lake.
Pretty much all electric models that are currently on the market come with a 12v motor, which is quite standard across the board. Where various models differ is in how much water they can pump out per hour, which is measured in GPH (gallons per hour). A product that claims it handles 500 GPH means that it can remove approximately 500 gallons of water from the bottom of your boat per hour. 500 is generally the minimum for electric units, and anything under that will most likely be designed for ponds, bait tanks, or aquariums. A product that claims it has a GPH of 2,000 means that it can remove up to 2,000 gallons of water per hour, and this is pretty much the maximum amount a single bilge pump can do.
Other Factors to Consider
No matter how well a bilge pump is made, keeping water away from the motor when completely submerged in water can be a very difficult task (even for some of the more expensive units). There are, however, a few inventive ways to keep water away from the motor at very little extra cost to you. Something that you might want to consider that will potentially double the life of your pump is to invest a little bit of money and time into butt splicers.
Butt splicers are simple wraps that fasten around exposed wires and shrink up around the wire when exposed to heat (like that from a simple pocket lighter). A box of 100 splicers costs about the same amount that you would spend on a box of nails, andthey can be used on various wires on your boat that you don’t want to be exposed to water. Just a few extra minutes to fortify your wires from water may end up saving you a lot of water in the long run.
You might be in hurry to rip the tarp off of your boat and get it into the water as soon as you possibly can to start enjoying the lovely weather and bring home some fresh fish for dinner, but before you do, it’s in your best interest to make sure that all of the mechanical components (especially the bilge pump) is in good working order. You can’t catch any fish if your boat ends up at the bottom of a lake.
Q: How does a bilge pump work?
A bilge pump is easily considered one of the most important component to the life of your boat. It works by sucking up all of the unwanted water that collects at the bottom of the boat and pushes it back out into the lake via a hose. It also serves as a great filter to keep all of the oil and debris that can live in a lake (or the ocean) away from all of the important working mechanisms of your engine.
Q: Do I need more than one?
Some fishermen and sailors choose to have more than one bilge pump for a number of reasons. First of all, you never know when a pump is going to stop working. No matter how well you take care of something, sometimes things just break, whether it be the hose or the motor itself. If you only have one pump and it breaks while out in the middle of a lake, you are left with no way to remove the water that you are taking on. The second reason for a second bilge pump is if a boater has an exceptionally large vessel that needs to remove more that 2,000 gallons of water per hour.
Q: Are they submersible?
It depends on the model, but most pumps are able to be completely submerged. In fact, it’s a better idea when shopping for a new unit that you keep an eye one for the ability to be completely submerged in water, because it will be more resilient, longer lasting, and better protected.
Q: Where are they located on the boat?
For electric models, they are placed in the bottom of the boat and the hose is run to the outside. For manual models, they are affixed to the floor of the boat and suck water up and out through a hose that hangs over the side.
Q: If my boat doesn’t have a motor, do I still need one?
These pumps are needed by any type of vehicle that floats on water. If it is capable of sinking, it can benefit from a bilge pump. It may be a good idea for your boat that doesn’t have a motor to tuck a manual pump under the seats just in case you find that you are taking on water.
Q: How do I clean it?
Since this pump is subject to all those icky mystery materials that live in the water, it can often become gunked up and not operate as well. Most models out there on the market are designed essentially the same, and it makes it super easy to clean. To clean your pump, all you have to do is detach the bottom from the motor, rinse it under some running water (or just swirl it around off the edge of the dock) and affix it back to the unit, and it will be ready to get back out there.
Q: Can I run my boat without one?
Just like you wouldn’t cook in your kitchen without a fire extinguisher, you should never subject your boat to water without the specific tools to keep you from taking on water. When it comes to your boat, it’s always better safe than sorry. Sure, you may not run into any problems taking your boat out on the lake for one short afternoon trip without the use of a functional bilge pump, but do you really want to take the chance when a new pump is relatively inexpensive?
Q: Are bilge pumps expensive?
Anytime something breaks on your boat, a sinking feeling begins to wash over you because you can just sense the big bill on the horizon. No need to fear when it comes to your bilge pumps, because even the most powerful and name brand models are offered at an incredibly affordable price so that you still have plenty of money to fill the tank with gas. Some of the models out there that are able to push out about 500 gallons of water per hour are offered at the same price as it would cost you to take a good friend out to lunch.
Q: What is a float switch, and do I need one?
A float switch is a sensor that can detect how much water is filling up the bottom of your boat and sends that information along to you (or the pump, so it turns on automatically). Therefore, yes, you need a float switch if you want a bilge pump that works correctly. Luckily, most of the products that are currently on the market either come with a sensor directly built into the pump so that it will turn on after the water gets so high and turn off once the water has been expelled. If the float switch is not already installed in the unit, some companies offer a separate float switch with with the purchase of a bilge pump.
Q: Are bilge pumps noisy?
Not all models are created equal, and some pumps are a little bit more noisy than others. In order to suck up water and pump it out of the side of your boat, you will be subjected to at least a little bit of noise. However, a little noise is a small price to pay for the security of knowing that your boat isn’t going to sink. If you don’t want to contend with the noise, you can always try and use a manual pump. But what it lacks in extra noise, it makes up in exhausting the user of the pump. Many users find that the extra noise doesn’t bother them too much, especially the ones that do not have to run constantly.
