SeaFlo Automatic 12V 750GPH and 1100GPH Bilge Pumps.

This Seaflow Manual and Automatic 750GPH or 1100GPH pump comes in the exact same sized housing so just select what capacity you are after when ordering. They are a direct replacement for Attwood pumps of the same sized base as well and they just clip on and off to the existing base. These 2 are fully automatic as well as manual override so when installing they have 3 wires (2 positive and 1 negative) so you just run one of the power wires to a switch on the dash and the other directly to your battery as that way when the battery isolation switch is in the off position the auto part of the pump will always work. the 750 GPH model has an output hose size ID of 19mm or 3/4 and the 1100 GPH suits a 29mm or 1 1/8 hose. Height of both pumps is 103mm.
