Buyer's Guide for Bilge Pumps

No matter how small or watertight your boat is, water will always find a way in.
Whether it’s capsizing a kayak, taking on water from a few waves while out in a dinghy or powerboat. Water gets in!

If you don’t empty it quickly it can cause damage, destabilize and even sink your vessel.

Selecting the right bilge pump for your craft

There is no need to go “overboard” when choosing a bilge pump. Having said that, there is no one size fits all.

For kayaks, dinghies, rubber ducks and other small crafts that don’t have on board batteries, the choices are fairly simple. You will need a manual bilge pump or one where a portable battery can be connected.

For larger boats like yachts, motor cruisers etc you will need an electric pump.

Pumping capacity

The logic here is fairly simple, the larger the boat, the larger the capacity of water your bilge pump or pumps should be able to handle.

Remember though, a bilge pump is not to stop you from sinking if you spring a leak in your hull. It is for getting rid of excess water from rain, occasional waves, etc.

Usually, a bilge pump capacity is measured in terms of gallons per hour (GPH).
If you have a small boar or kayak, then a small hand pump capable of pumping around 400 GPH is sufficient.

For a larger vessel, the same size pump is adequate, but you would want it to be automatic. You don’t want to pump 400 gallons of water by hand for an hour TRUST ME!!
