This pump has a solid construction and is very easy to install with a universal mounting base.

Let’s continue our search for the best bilge pump by taking a closer look at the Seaflo Automatic Submersible Boat Bilge Pump.
This bilge pump by Seaflo is another compact but efficient and reliable pump for your watercraft. It is extremely easy to both install and perform maintenance on when needed. It is built from stainless steel and other corrosion resistant materials and used watertight seals in key areas to provide a pump with extra longevity.
If you are looking for a bilge pump for your boat docked in the marina, this particular model might be a better fit for you as it is already designed with an internal float switch.

These models feature 36” of 16 gauge wire which is more than enough to install in key areas while still being able to run to a power source without extra materials. The wire cables are also caulked to prevent moisture seeping through the jacket.
This is a well-designed pump that uses quality and state of the art materials giving you a reliable bilge pump that you can count on for several years of use including a permanent-magnet motor, stainless steel shaft and components, and steel reinforced seals.
These pumps weigh in at a little over 1lb and are still relatively compact. They are incredibly easy to install and only run off of 12V. These pumps utilize a ¾” bilge outlet and have an off, on, and automatic setting with the built-in float switch.

The body is made with corrosion-resistant materials and watertight design that gives the motor great longevity. It also comes with a limited three-year warranty.
