Automatic Vs Manual Bilge Pump – Which Is Preferred?

When you want to get rid of bilge water faster, then an automatic one proves to be the most beneficial. A manual bilge pump may require a lot more effort in case of emergencies. We have discussed both types of pumps above, and you can refer to their features and select the one which sinks in with your boat requirements. Our personal preference is the automatic bilge pump as it is convenient, can sense water on its own, works efficiently to remove water, and prevents damage of any kind. If the automatic pump loses its hold or gets mal-functioned due to any of the reasons, then a manual bilge pump can be kept as an alternative.

Choosing The Best Bilge Pump – The Ultimate Guide

The Boat Type:

It greatly depends on the type of boat which pumps you choose. For example, for an outboard motor, a handpump is sufficient to draw out water. A bit larger boats such as the ski boats, require an electric pump which is submerged in water. The offshore racing boats may require two bilge pumps (one at the cockpit and others on the deck).

There are coastal and powerboats too, which may be used from the calm waters to the roughest of marine environments. Buy a bilge pump that caters to your requirements, as the rough waters will give you more chances of water getting in your boat or vessel. Bilgewater may reach from any of the sources, and the situation should be studied prior.

Boat Size:

As the rule of the thumb, the boat size decides the size of the pump, and this goes parallel. If the boat size is bigger than a small pump will work well, but larger sized boats will require a bilge pump of greater capacity.

If you are covering wider water areas, then a pump with high-power is the need and the GPH should be great, if an electric pump is chosen. Another important factor is the freeboard consideration that you have, as the boats with low hull volumes are the victims to suffer from heavy water. Larger freeboards make you get rid of bilge water more conveniently.

Even the smaller sized boats require robust pumps to clear water as fast as possible.

Bilge Compartments:

Separate bilge compartments call for more monitoring and planning. Since the water in different sections of your boat will require more time to be cleared, and this may require more than one pump. Every segment will need a sperate pump. The diaphragm pump may be of use when clearing water of every bilge is required. These pumps are equipped with numerous intake hoses for different boat parts. Even an electric pump can be connected to deal segmented bilges.

Pump Switches:

The modern pumps and the ones we have explained are integrated or built-in switches that can sense water on their own. This is possible with an automatic bilge pump. These switches work automatically with sensing technology while the pump system spins intermittently after they come in contact with water. These switches prove to be environmentally-friendly and a great feature overall.

Access And Installation:

If you are opting for a manual pump, then installation and access isn’t a hassle at all. The automatic pumps require a bit of expertise to set them up. You can follow the manual instructions and do the needful. In case of any troubles, some professional help can be taken for easing out the installation and accessing tasks.

Capacity:

The GPH (gallons per hour) requirement of your boat increases, with its size. For bigger boats, more than 1000 GPH is required, and the smaller ones can work with a bit lesser than this. The amount of water which is pumped out is decided with the help of this.

Best Bilge Pumps

The capacity feature is limited to the automatic pumps as the manual ones are entirely dependant on your capacity to drain out water.

Material:

The marine water may be salty, so the material used to build the pump should be water-resistant along with an anti-rust quality. It is preferable to have shafts of stainless-steel and the casings of plastic as the marine environments may turn very harsh on them. Any pump that won’t possess quality material is bound to wear and fail soon, and this will waste your money too.

The Crux:

You must be fairly confident by now after reading so much on the best bilge pumps. We recommend you to purchase an automatic bilge pump to simplify your water pumping task, but the other alternative could be the manual one if it suits you.

Consider each and every aspect seriously after you choose the best bilge pump for your vessel.
