Johnson Bilge Pump Buying Guide

You need a quality bilge considering you are likely to use it every time you use your boat. There are factors you should consider before you purchase a Johnson bilge pump. Taking these factors into consideration helps you get the right bilge pump for your boat.

Boat Type

If you have a small boat with an outboard motor, you may not need an electric pump. Any water collected is easily taken out using a hand or manual operated pump. For slightly larger boats like ski boats, you need to consider an electric bilge pump. Get one that is submersible, considering such types of boats normally take in more water than other boat types. 

Offshore racing sailboats require two bilge pumps. One is operated below deck while the other is operated on the cockpit. For offshore or coastal boats, you need several pumps. Ideally, each compartment with a tendency of filling with water needs a pump. If you have a powerboat and you use it on calm waters, a smaller pump will suffice. 

Boat Size

A rule of thumb is the bigger the boat, the larger the size of a bilge pump. Keep in mind to consider the boat type and the type of waters you are likely to encounter. 

Look out for a GPH (gallons per hour) rating on any electric pump. It’s the rate of water the gadget will clear in an hour. You will notice the rating varies by a lot. Get a higher rating if you have a large boat. 

Do you have a large boat that sits low in the water or a small boat that sits high in the water? The amount of freeboard is a crucial factor in determining the right pump for your boat. A low hull volume increases the amount of bilge water. If you have a small boat, an average-sized bilge pump is recommended, especially if you mostly travel on rough waters.

Electric vs. Manual

When you compare the two, it’s without a doubt electric models clear out more water than their manual counterparts. However, you may use manual models on boats such as a kayak. Additionally, if your boat doesn’t have an electrical outlet or a 12 volt DC line, then the manual pumps are your only option.

Take note if bilge water goes beyond the bilge, it may affect your electrical system. This may mean your electrical bilge will stop working due to a lack of power. If you have a large boat and you travel a lot, it’s wise to have a manual pump just in case the electric one fails. 

Bilge Compartments

Segmented bilges mean water can get trapped in different areas of the boat. This means having a pump in one area is pointless. A good solution would be getting a diaphragm pump.

These units have several intake hoses that can be relocated to areas where they are needed. If you can’t get a diaphragm bilge pump, get several electronic units. This way, you can clear water in all areas with bilge water. 

Pump Switches

All pumps are turned on automatically via one of the three types of switches. The first type is known as an integral automatic switch. It’s located inside the pump and turns on when it comes into contact with bilge water. An alternative system works by spinning the pump intermittently to determine if there is bilge water. 

The second is known as a float switch. It works by turning on the pump the moment it senses bilge water. If you don’t have this type of switch, don’t worry. Most pumps are compatible with a spate float switch. In the past, they used to contain mercury. However, current float switches don’t have mercury, and they are environmentally friendly. 

Lastly, some have plastic housing and can detect water. They are designed to turn on when they detect water. The type of switch is not as important as making sure it works. An automatic bilge pump is a safe and convenient pump. 

Diaphragm vs. Centrifugal

Centrifugal pumps sit in water and start working once they are surrounded by water. They are known not to be self-priming. It means they use their vanes to draw water and push it outside. Usually, they have a strainer that stops them from getting clogged with debris. 

Diaphragm pumps are self-priming. They take in water through an intake hose and take it outside the boat. Some come with a strainer, while others don’t. If yours didn’t come with a strainer, you could purchase it separately. 

The most widely used are centrifugal. They are popular for their low cost, ability to handle small debris, simple design, and high capacities. In large ships, these are the most used bilge pumps. They are the best option when you want to move large quantities of water. 

Capacity

The capacity of bilge pumps is measured in GPH (Gallons per hour). For instance, if you see a product labeled 600 GPH, it means it can remove 600 gallons of water every 60 minutes. It’s a rating that is used on all electric bilge pumps. 

If you plan on buying a bilge pump for your boat, try and go for 1,000 GPH or more. This is the recommended size for most small to medium-sized boats. The size of your boat determines the GPH you choose. If you are not sure, consult the seller of the products to get an idea. 

Material

Normally, ABS plastic is the material used for the casing of a pump. It is known as a resistant and reliable material. You want to ensure the material used will protect your device’s wiring and ignition.

You also want to get the best corrosion protection. For the shafts, go for those made from stainless steel. The quality of material used on your product will determine its efficacy and durability.
