The Whale Supersub 500 GPH is the smaller of the two Supersub low-profile bilge pumps, sized for small boats and secondary bilge areas. Its narrow body fits deep into tight spots where a standard pump will not go. It runs on 12V and is non-automatic, so it pairs with a switch or float.
Both the outlet and the pump body rotate, letting you aim the discharge hose where it needs to go in a cramped space. Power draw is very low for efficient operation. The snap-fit assembly opens without tools for cleaning.
Five hundred GPH suits light-duty bilge pumping or as a secondary pump; choose the 1100 GPH model for more capacity. Wire it with proper circuit protection and a float switch for automatic operation. Browse more Bilge Pumps for other pumps.
