Bilge Pump Buying Guide

Basic Types

Basically, there are two types of water boat pumps, including the centrifugal pump and the submersible pump. The centrifugal pump is said to win the greater confidence among the users because its counterpart is harder to repair. However, centrifugal pumps are also believed to be unreliable than the submersible type. The Rule submersible pump, however, is an exemption to this rule.

Manual Versus Electric Power

High-powered centrifugal pumps are inexpensive, and these types are very easy to install. However, such devices could be ineffective if the boat’s electrical system fails. With this regard, the experts highly recommend having an additional high-powered manual diaphragm pump.

Manual pumps are capable of moving a substantial amount of water, usually up to 30 gallons. Thus, this could be a very tiring task for both the user and the pump, especially when the location of the pump requires the user to be in an awkward position. On that note, an effective pump and the proper installation location are very crucial. So, when choosing a manual water pump for boats, it is most essential to take note of the gallons per stroke, including the ergonomics of the entire pump.

Meanwhile, an automatic bilge pump requires a separate water-sensing switch or an automatic pump. Experts say that the main disadvantage of this device is that the user might be unaware of the pump’s operation once a steadily increasing leak develops. This could become catastrophic and could go beyond the real capacity of the pump.

Bilge Pump Selection

Before even placing your order for the best bilge pump, there are more key pointers to take note of. Whether this device is for your fishing boat, personal watercrafts, or similar purposes, please try to keep in mind the following tips.

Should the bilge on a boat a regular pump or a heavy-duty one? The answer depends if you can afford the heavy-duty bilge pumps as these devices are relatively expensive, compared to the standard versions. If you can, it is always best to buy and have both types. Remember that you should have at least 3 pumps on a small boat.A heavy-duty bilge pump is highly recommended for commercial boats, and fishing boats as oil spillage into the bilge is a frequent occurrence.

The heavy-duty pump is likewise ideal for boat plumbing that involves debris and dirty water.For the unsure consumers, going for the heavy-duty, such as the Rule submersible bilge pump 500 gph is always a sensible decision.But, for pleasure watercrafts, going for the regular or standard range of pumps is common.A small electrical pump is typically automated to begin pumping water once the water level reaches a specific point. This comes in very handy once your boat starts to get filled with water as you’re asleep or away from the boat.A manual or hand bilge pump can pump up to 30 gallons of water in every minute, a tremendous capacity indeed.

Pump Capacity

Moreover, the pump capacity is equally an important factor to consider. In minutes, the water can take over your boat, but, having a pump with the right capacity can surely solve this problem. However, not all boats, especially the small ones can carry the largest possible pump.

Well, for small boats, you can settle with the Rule 2000 or any of the above-mentioned pumps. As mentioned above, all the brands can be very useful for different routine pumping tasks and emergency purposes at the same time. Once you have decided to get one out of the bilge pump reviews above, it is always sensible to have a backup – a pump with greater pumping capacity as pumps could also fail anytime. For boats that measure 40 feet and above, having at least 8000-gallon/hour pump is the ideal starting point.

Problem Solver

In a nutshell, a bilge pump should at least minimize the problem, if not solve it permanently. The very first step to achieving the bilge pump nirvana is ensuring that your boat’s bilge is free of debris, trash, and other unwanted objects. More so with older boats, a routine bilge cleaning is critical, but also with new boats. Oily bilge residue must be cleaned up as well, disposing of such residue properly. By doing this, the boat bilge pumps will work more efficiently and faster.


Certainly, there are various manufacturers and brands of the best automatic bilge pump such as Shoreline, Rule, and Johnson bilge pumps for boats. Choosing a reliable dealer of such devices is equally essential, ensuring the quality, durability, and warranty all at the same time.

To maximize the efficiency of this safety device, it is always sensible to keep discharge hoses as little as possible because long hoses tend to have more resistance, reducing the performance of any bilge pump. Using a smooth boar hose is also essential throughout the task because ribbed bore decreases flow capacity, including the pump performance.

Experts also recommend users to follow the recommendations and instructions from the manual or the manufacturer, especially when it comes to wire sizes. This is to prevent voltage drop. Finally, maximizing the capacity of the best bilge pumps can be attributed to using waterproof butt connectors for all the wiring areas in the bilge.

Nonetheless, reading the bilge pump reviews, customer ratings, and recommendations are equally essential for a potential buyer and user of bilge pumps. These materials will help in narrowing down the choices, in spite the overwhelming options on the market while helping the buyer to arrive at the most reliable, most efficient, most durable, and no less than the best bilge pump possible.
