Whether you’re a dedicated boater or an occasional one, choosing the right bilge pump is essential to keeping your boat running smoothly. The bilge pump is an essential part of any vessel, as it ensures that excess water and debris are eliminated from the craft’s hull for it to remain safe and seaworthy. With so many different options on the market today, deciding which bilge pump would work best for your individual needs can be overwhelming – but we’ve got you covered! This comprehensive buying guide provides all the information you need to make an informed decision and get back out on the water safely with a reliable bilge pump.
Automatic vs. Manual:
Manual bilge pumps, as the name suggests, require manual operation. These pumps can range from simple and inexpensive options to more advanced and higher-priced models. However, even the basic manual pumps are generally affordable and highly reliable, making them a practical choice for small boats or as a backup system. One key advantage of manual pumps is their simplicity and absence of electrical components, which reduces the risk of failure due to water damage or power issues. Whether you opt for a budget-friendly manual pump or invest in a more advanced model, they provide a straightforward and dependable solution for removing water from the bilge, providing peace of mind for boat owners.
Automatic bilge pumps come equipped with water level sensors and switch on autonomously when the water reaches a certain level. This feature takes the worry out of monitoring and operating the pump, especially useful in conditions where rapid water accumulation occurs or when you are away from your boat. However, they are slightly more expensive and complex, needing a reliable power source and occasional maintenance.
Electric bilge pumps come in different configurations, including options with or without a float switch. A float switch is a separate or external device that is connected to the pump and controls its operation. It automatically turns the pump on when the water level in the bilge reaches a certain height and turns it off when the water level drops. This feature provides convenience as it eliminates the need for manual activation of the pump. Electric bilge pumps with float switches are highly efficient in automatically removing water from the bilge, ensuring that it remains at a safe level.

Pumping Capacity:
Always consider the size of your boat and the volume of water it could take on when deciding on a bilge pump. Pumping capacity, measured in gallons per hour (GPH), indicates the amount of water a pump can remove in an hour under test conditions. As a rule of thumb, larger boats or those designed to tackle rougher seas will require a bilge pump with a higher GPH rating. However, even for smaller crafts, it is wise to err on the side of caution and opt for a pump with a larger-than-needed capacity. This provides an extra safety margin for unforeseen circumstances like heavy rain or higher-than-usual water ingress. Be aware, though, that a higher-capacity pump will consume more power.

Noise Level:
When considering a bilge pump, factoring in the noise level produced during its operation is important. Some pumps are designed to operate more quietly than others, which can be a significant advantage if you spend long periods on your boat. A quieter pump may add to your comfort, especially during night cruises or if the pump has to be used frequently. However, a very silent pump may offer a different reassurance of functionality than a louder pump. It’s crucial to balance noise level and efficacy, ensuring the pump is both unobtrusive and capable of signalling its operation. An example of a quiet model that customers often mention are:
