  • 4 Year Warranty!

The Seaflo-Automatic 750GPH pump is one of the few pumps that balance functionality with practicality. For instance, besides packing a huge flow rate, it also features a built-in sensor switch. This switch is automatically activated when the water levels rise. And thanks to its generous flow rate, you can count on it to drain out the water fast and efficiently.

Besides the well thought out mechanism, the Seaflo is pretty durable. A closer look at its components reveals that they're made of high-quality, rust and corrosion resistant stainless-steel parts. It's housing is also pretty well-made as it comes with a tough plastic which is capable of withstanding all kinds of torture.

In addition, it is energy saving, because power is only used when water levels rise. That’s when the internal float switch activates the pump. The unit has an ignition mechanism to protect it against high currents.

Pros
  • Durable
  • Automatic with manual operation
  • It is fast
  • Protection against high currents
  • Affordable
Cons
  • Only starts working when water levels are sensed

The Bilge Pump Buying Guide

Much as this is an important accessory, you want to be sure that you only work with the best there is. That's precisely what this guide is meant to help you do - find the best pump for your needs.

Pumping Capacity

Normally, the bigger your pump is, in terms of capacity, the better. A big pump will, no doubt, be in a position to lift the water to a greater height. What's more? It should be able to help you drain the water as fast as possible.

Installation

While it's recommended to have a professional install it for you, finding one that's easy to install can be a major plus. Most importantly, the pump should be installed in a position that's easily accessible. That way, you can have an easier time removing the debris and cleaning its intake at all time.

The Flow Rate

Basically, the higher the flow rate, the more effective a bilge pump is likely to be especially during emergencies. If you own a small boat and typically tour rivers and small lakes, a 600 GPH pump would suffice. However, if you like visiting choppy waters and oceans, it's important to get a 2000GPH or thereabouts.

Usable in Saltwater Usability

It goes without saying that you need to use a pump that's well-made. Ideally, it should come with non-corrosive parts especially if you tend to tour saltwater surfaces frequently. Ideally, it should have stainless steel shafts.

The Ability To Operate Quietly

Because these pumps are motor-powered, some of them tend to be extraordinarily noisy when in use. If you value quietness, make sure the bilge pump you opt for is capable of delivering a vibrationless and silent operation.

Built-In Sensors

Some water leaks may occur even without you knowing it. And in that case, it makes perfect sense to have an automated, electric pump. Such a pump should have an internal float which is automatically activated as the water level rises.

Installation Tips

The following basic installation tips for bilge pumps will help you ensure that the entire system is properly set up. They include:

  • A short discharge hose should always be used to reduce resistance and improve pump performance.
  • A vented loop is your best bet especially with the threat of the kayak or boat immersing.
  • Always use waterproof butt connectors for all the wiring connections within the bilge area.

Which One Is The Best?

If you have a large capacity boat and typically frequent choppy waters and volatile oceans, we'd recommend the Seaflo 2000 GPH for you. It comes with heavy-duty motors and is capable of delivering a high capacity output.

Otherwise, if you're scouting for the best bilge pump for kayaking, we'd vouch for the Seaflo Automatic Submersible pump. With a 750GPH flow rate and a built-in float switch, this is, no doubt, a great pump for the price.


Final Thoughts

The perfect bilge pump doesn't exist. Different kinds of water environments mean that there's no one-size-fits-all system. And that's why you need to pick one that seems to meet your needs in line with your style of fishing.
