Top 110V Bilge Pumps

A bilge pump clears water from the bilge – a watertight area below the deck of a boat. This is usually essential when there’s a breakdown or emergency on board, as it allows the boat to float and stay afloat.

A good bilge pump can save your boat from sinking. A 110V bilge pump is reliable and easy to use, requiring little maintenance. They can be portable, so you can use them anywhere on your boat.

What is a Bilge Pump?

A bilge pump is a vital part of any boat, and a 110V one is especially important because it can handle high water pressures.

A typical bilge pump operates by sucking water out of the boat’s hull and through a discharge pipe. This process helps to remove excess water from the ship, keeping her afloat in tough conditions.

If your boat doesn’t have a bilge pump, now is the time to get one. A bilge pump can help prevent your boat from sinking in high water conditions, and it’s an essential part of any emergency preparedness plan.

110 Volt Bilge Pump Buying Guide


Many different pumps are available for 110V usage, so it is important to choose one that will fit your specific needs. The type of bilge pump you need will depend on the type of boat you have.

There are electric bilge pumps, manual bilge pumps and even portable bilge pumps.

Size of the boat

The bigger the boat, the more power your bilge pump needs to work properly. So it’s important to choose a pump that has enough power to clear water from your vessel safely and quickly.

Most bilge pumps come in capacities from 1/2 gallon up to 10 gallons per minute, so make sure you find the right size for your boat or vessel.

Bigger pumps can discharge more gallons per minute, which is important if your boat has a large hull or you frequently fill up the bilge with water.

Installation (boat vs permanent mooring)

Manual pumps will work better for boat installations while electric pumps are more versatile for permanent moorings.

Some pumps are easier to install than others, so make sure that you consult with an expert if you are not familiar with mechanical repairs or installations.

The mounting system determines how the pump will be installed on the boat and whether it will be fixed or portable. Fixed pumps are mounted permanently on the boat’s deck while portable pumps can be moved around as needed.

Durability and longevity of the pump

Make sure that the brand you are considering has a long history of producing quality pumps, and that the pump is built to last.


Some pumps are designed specifically for use on boats, while others may work fine on vessels that do not have a dedicated bilge pump location. It is important to consult with an expert before making a purchase to ensure compatibility and quality.

The power of the pump

Higher powered pumps can work faster to remove water from a bilge, and are often easier to use than lower power models.

The power source is usually either battery or AC. A battery-powered pump is more portable and can be used in situations where there is no access to an external power supply. An AC-powered pump is easier to install because it plugs into a standard electrical outlet.

How easy it is to operate

Some pumps have buttons on them while others require using an app or remote control. Make sure the pump you choose is easy to use before making your purchase.

Are there any benefits to using a bilge pump over other types of pumps?

There are several benefits to using a bilge pump over other types of pumps.

Bilge pumps are versatile and can be used in numerous applications. They also have a longer lifespan than other types of pumps, making them more affordable overall. Bilge pumps are also easier to operate.

They typically have fewer moving parts, making them less likely to malfunction.

Some potential drawbacks to using a bilge pump over other types of pumps include the possibility that they may not be able to handle particularly large or heavy objects.

Additionally, bilge pumps can be more expensive than other types of pumps, so users should factor this cost into their decision-making process.

How do you wire a bilge pump directly to a battery?

If your bilge pump has an onboard battery, and you want to use it without having to run an external cable all the way to your boat, you can wire it directly to the battery. This is a convenient and easy way to keep your pump running without having to go outside. Here are the steps you need to follow:

1. Locate your bilge pump’s electrical connector.

2. Connect the electrical connector to the battery.

3. Connect the other end of the electrical connector to an outlet on your boat.

What size bilge pump do I need for a 20-foot boat?

A 20-foot boat typically needs a 3 or 4 horsepower bilge pump, but if your boat is more than 30 years old or has sentimental value, you may want to upgrade to a 5 or 7 horsepower pump.

This will ensure that the pump can handle larger boats and heavier seas.

How many GPM should a bilge pump have?

A bilge pump should have a flow of at least 3 gallons per minute (GPM) to be effective. This is the minimum amount of water that will move through it in order to clear any debris or sewage from your boat’s hull.

If your bilge pump is not flowing enough water, then you may need to replace or upgrade it.

Where should I put my bilge pump outlet?

Some bilge pumps require a dedicated outlet in order to function, while others can be plugged into an existing electrical box.

When choosing where to place your bilge pump outlet, it is important to consider the layout of your boat and the location of any Electrical Systems Compartment (ESC) or Wet Bar. If you have limited space, then placing the pump near these areas may be preferable.

Additionally, if there are potential hazards around your bilge areas such as water lines or movable objects, adding an obstruction-free plug will prevent accidental activation of the pump.


Best for Kayaks and Canoes (Manual Pump): In very small watercraft, it doesn’t make sense to have an electrical bilge pump. Kayak and canoes are often unpowered. While keeping a bucket for bailing in the boat does work, a manual pump like the Better Boat Bilge Pump* takes up less space in already cramped quarters.

Best Overall: There is a lot of variability in boats, so it’s hard to say which is the best for your boat unless you know your needs. One brand that does a good job building durable pumps with ratings at regular intervals (500 gph) is Rule.

For a smaller boat, you could purchase a Rule 500 GPH*, which only pushes about 8.3 gallons per minute. But you can also upgrade in 500 GPH intervals up to 2000 GPH, which is a very fast rate (33 gallons per minute). You can match the appropriate gallons per minute to your boat, taking into account the size and number of leaks.

The Rule brand can be more expensive than others, but being able to empty water quickly is essential in rough conditions.

Key Takeaway

A good 110-volt bilge pump will be able to evacuate water in the hull of a boat quickly and easily, while also having a durable build. It should also integrate easily with your boat’s electrical system.

Additionally, it is important to consider the price point of the chosen model, as well as its compatibility with your specific needs.

Most bilge pumps have features to consider as well, like float switches or the ability to automate pumping when necessary.
