5 Best Submersible Bilge Pumps For Your Boat: The Ultimate Guide 2024

Submersible bilge pumps are an essential tool for any boater who wants to keep their vessel afloat. These pumps are designed to remove water that has accumulated in the bilge, which is the lowest point in the hull where water naturally collects. Submersible bilge pumps are so named because they are designed to be installed below the waterline and operate while fully submerged.

When it comes to purchasing a submersible bilge pump, there are a few critical things to consider. First and foremost, you need to make sure that the pump is the appropriate size for your vessel.

The size of the pump you need will depend on the size of your boat and the amount of water you need to move. Additionally, you should consider the pump’s flow rate, which is the amount of water it can move per minute. Other factors to consider include the pump’s power consumption, durability, and ease of installation.

We spent hours researching and testing several submersible bilge pumps to identify the best options on the market. In the following sections, we’ll share our findings and help you choose the right submersible bilge pump for your boating needs.

Buying Guide

When it comes to choosing the best submersible bilge pump, there are a few key features to consider. Here are some things to keep in mind:

Flow Rate

The flow rate of a bilge pump is measured in gallons per hour (GPH) and determines how quickly it can remove water from your boat. It’s important to choose a pump with a flow rate that matches the size of your boat and the amount of water that needs to be pumped out.

Automatic vs. Manual

Automatic pumps turn on when the water level in the bilge reaches a certain point, while manual pumps require you to turn them on and off manually. Automatic pumps are generally more convenient, but manual pumps can be useful as a backup in case of a power outage or other emergency.

Voltage

Most submersible bilge pumps run on 12V DC power, but it’s important to make sure that your boat’s electrical system can handle the current draw of the pump you choose. If you have a larger boat, you may need a pump that runs on 24V DC power.

Size and Installation

Make sure to choose a pump that will fit in the available space in your boat bilge and that is easy to install. Some pumps may come with mounting brackets or other installation hardware that can make the process easier.

Materials and Durability

Look for pumps made from high-quality materials that are designed to withstand harsh marine environments. Stainless steel or bronze housing can help prevent corrosion, and a sealed motor can help protect against water damage.

Other Features

Some other features to consider include:

• Float switches that automatically turn the pump on and off
• Built-in check valves to prevent backflow
• Low amp draw for efficient operation
• Easy-to-replace cartridges for quick maintenance

By considering these factors, you can choose a submersible bilge pump that will keep your boat safe and dry.
