Attwood Tsunami MK2 T500 Manual Bilge Pump w/Installation Kit - 500 GPH & 12V

The Attwood Tsunami MK2 T500 Manual Bilge Pump with Installation Kit is a reliable, hand-operated emergency dewatering solution built for boaters who take water management seriously. Whether you're running a center console, cruiser, or auxiliary vessel, unexpected water intrusion can occur, and when it does, you need a pump that works without relying on electrical systems or engine operation.

This manual bilge pump delivers a capacity of 500 GPH, making it capable of handling moderate water accumulation in confined spaces and emergency situations. The MK2 T500 operates via manual lever action, requiring no batteries or 12V power source to function—a critical advantage during system failures or extended offshore passages. Its robust construction withstands the corrosive marine environment, and its straightforward mechanical design means fewer failure points compared to electric-only alternatives.

Experienced cruisers and offshore anglers commonly carry the Attwood Tsunami MK2 T500 as a backup system or primary dewatering tool for smaller vessels, sailboats, and tenders. Its compact footprint (7 x 6 x 9 inches) fits easily in engine compartments, bilge spaces, and locker areas without consuming valuable cabin real estate. The included installation kit contains all necessary through-hull fittings and hardware, eliminating the guesswork during setup.
