The Importance of a Reliable Bilge Pump for Boat

Picture this:

It’s a perfect day on the water. 

The sun is shining, the wind is in your hair, and all seems right with the world. 

But, just like the unpredictable nature of the ocean itself, the calm can quickly turn into a raging storm when you are on a boat. 

For any knowledgeable or experienced boater venturing into the unknown, blue waters, there is one tool aboard a boat that is simply unnegotiable. 

That tool is a bilge pump for your boat!

The bilge pump is the one onboard tool that always works for your safety on the water. 

Often, it does so without ever being noticed. But don’t underestimate its power.

While you are enjoying your day on the ocean, lake or other body of water, this little machine works tirelessly to keep your boat dry and free from water that builds up in your bilge. 

For any boater who has been on the water for a minute, you know what a bilge pump is and why they are so critical to your boating success. 

In fact, you’ve probably had one go out and can bear witness, firsthand, to how critical this little pump can be. 

If you’re new to the water, a bilge pump is simply a mechanical pump that takes the excess water in the bilge of your watercraft and pumps it overboard to help keep you floating. 

Bilge pumps can be automatic, triggered by the use of a float switch that turns on when enough water collects, or manual, that is run by being turned on at a switch.

Either way, this powerful little tool is the workhorse of your treasured vessel. 

In this article, we embark on a guide to some of the most popular and reliable bilge pumps that boaters can find online today. 

So tighten your life jacket and let’s navigate the waters of this absolute necessity, a bilge pump for boat!

A Bilge Pump for Boat Buying Guide

As we’ve outlined in the products above, a reliable bilge pump is truly the unsung hero and first line of defense for safety in boating.

Whether you are headed offshore to hook into a school of tuna, or headed deep within freshwater waterways, having a reliable bilge pump can be the difference between a safe return to the dock or something much more unpleasant.

However, with so many options for bilge pumps for boats, it can be a bit overwhelming to choose the pump that is best for your unique boating needs.

That’s why we’ve put together the following section for your consideration when choosing the right bilge pump for your boat.

The following considerations will equip you with the best knowledge available to help you choose the best-fit bilge pump for your vessel while providing you with the peace of mind to leave the dock with confidence.

Let’s dive in!

 

Pump Capacity and Flow Rate:

The first and most important consideration for any boater when it comes to a bilge pump centers around the pump capacity and flow rate that the bilge pump produces.

The bilge pump needs to be able to keep up with and handle the influx of water that gets into your boat (and ultimately the bilge) from rough seas, rain, leaks and other intrusions.

When choosing a bilge pump for boat, it’s important that you look for a pump that is built to handle the flow of water for a boat that is your size and type to ensure that it can handle the expected and unexpected flow of water you might encounter on the water.

Be sure that the pump you choose is built to handle the flow of water in your bilge over and above what you expect.

That way, you can be sure that you have a pump that is large enough to handle even unexpected issues on the water, related to water inside your vessel.

With a bilge pump, this is one place you do not want to be cheap and choose a machine that is less than what you need to save a few bucks!

Do yourself a favor and know that your bilge pump is built to do the job for you so that you can have peace of mind on the water.

 

Consider your Power Source:

As you probably noticed in our list of recommended products above, there are two primary types of bilge pumps, electric and manual, or hand-operated.

While most boaters opt for electric pumps for convenience and capacity, it is usually a good idea to have a hand-held or manual bilge pump somewhere on your boat in case of power failures.

Since most boaters are looking for an electric bilge pump, it’s important to consider your power source for your boat and how it will connect.

Most manufacturers make their bilge pumps straightforward and easy to connect, but it is still critical for a boater to know how far away from your batteries or other power sources your bilge pumps will be so that you can plan accordingly.

When purchasing, make sure that your chosen pump is easily installed to integrate with your existing power systems, and of course, that your power systems have the power available to run your pump, especially on demand.

 

Manual vs Automatic Electrical Pumps

Next up with respect to things to consider when purchasing a bilge pump for boat is what type of electric pump you need for your unique watercraft.

Bilge pumps normally come in two different types: those that are automatically triggered to pump water overboard, and those that are manually engaged.

Automatic pumps come with included sensors, float switches, or other devices that tell the pump when it’s time to power up and pump water without you as the Captain needing to do it manually.

Manual bilge pumps, as you probably guessed, are pumps that are activated at a switch to turn on and start working.

For most boaters, it is strongly recommended that you have at least one automatic pump working for you on your vessel at all times.

An automatic pump takes the guesswork out of the boating equation, doing the work for you without you seeing it.

In many cases, boaters will use manual pumps in deeper sections of the bilge or other sections of the boat that need regular but not constant monitoring of water levels.

With the flip of a switch, these areas can be drained through the use of a manual bilge setup.

 

Reliability of the Float Switch

One of the most important aspects of any automatic bilge pump is the float switch that tells the machine when to power up and start pumping water out of a boat.

The next consideration in our bilge pump buying guide is choosing a float switch that provides powerful reliability on the water.

Float switches come in a number of different types for boaters.

The most common is the lever-style setup that rises with the level of the water in a bilge and turns on once the float is triggered above a specific angle.

Since the float switch is the mechanical apparatus that tells the machine when to power on and off, it is critical to purchase a switch that can last through a lifetime of on/off iterations on your boat.

Cheaper, discount model float switches might save you a couple bucks, but do you really want to stake your boat on something so critical over a few dollars?

Be sure to choose a float switch that is well-reviewed, and able to last he lifetime of your pump itself.

 

Sizing and Installation areas:

The next consideration for any boater looking for a new bilge pump for boat is the overall size and how the pump will install in the unique bilge sections of your boat. 

Every boat’s bilge is a little different. 

Typically you will want to install your pump at the lowest part of your bilge so that you can maximize the ability to pump all the water out of the bilge while on the water. 

Before you buy a new pump, make sure that it will fit nicely in your bilge area and understand how you will mount the pump for maximum efficiency. 

Also, be sure that where you choose to install the pump is easily accessible as you will need to be able to get to it quickly in the event of any emergencies. 

 

Alarms and Monitoring:

Next up, alarms and monitoring of your bilge system. 

Some more advanced bilge pumps will come with more advanced monitoring or warning systems to help boaters know if anything is going wrong with their bilge pump systems. 

If you have a larger vessel or are powering a network of bilge pumps in hard-to-reach places on your boat, choosing a system that has the capabilities to provide alarms and monitoring may be the best-fit solution for your needs. 

While most entry-level boating bilge pumps will not require this type of additional solution, it is critical to be prepared on the water especially if it can help your safety and peace of mind. 

 

Pump Durability:

Remember! Your bilge pump is working even when you aren’t!

It works at the dock when you are away. 

It works offshore while you are focused on your next catch. 

It turns on and off thousands of times in a week. 

So be sure to choose a model that is durable and quality built to provide you with the confidence necessary on the water. 

 

Energy Efficiency:

Next up on what to consider with your bilge pump is the overall energy efficiency of your chosen model. 

You do not want to select a pump that constantly drains your batteries of energy and is an overall load hog. 

Select models that conserve your battery power, especially on longer voyages. 

 

Customer Reviews & Brand Reputation:

While this is obvious to any boater, choosing a pump that is quality built by a trusted marine brand that has powerful social proof about its durability and reliability should be at the top of your list when purchasing a bilge pump. 

Select models that other boaters can vouch for on the water in terms of what you need to keep your boat high and dry. 

Choosing from a brand that is trusted in the marine space can help you avoid unexpected pitfalls that untrusted, non-marine brands may cause as a result of their inexperience with boat-specific products.

 

As you can see, choosing the right bilge pump for a boat can require some thought and research. 

In this article, we have tried to shine a light on a list of trusted and well-reviewed bilge pumps to help you narrow your options. 

However, it’s important that you choose your product based on the unique needs of your life on the water!
