What to Compare Before Buying

- Output needs: The stated 1200GPH flow rate is the main figure to compare with the amount of water you want the pump to move.

Compatibility, Size and Fit
This pump is intended for a 12V setup and uses a 28.5 mm (1-1/8″) outlet. Those two details matter most when checking whether it matches your boat and plumbing arrangement. The physical size, 155 x 90 x 115 mm, is also important if the installation area is tight.
What Else You May Need
A compatible hose or fitting for the 28.5 mm (1-1/8″) outlet, along with a suitable 12V power setup, may be needed for installation.
Before You Decide
Confirm the 12V electrical setup, the 28.5 mm (1-1/8″) outlet size, and the available installation space before choosing this pump. The built-in float switch is part of the product configuration, so you do not need a separate float switch for the stated automatic operation.
