Manufacturer description

HYDRA™ Automatic Bilge Pump - 1100 GPH - 12V

The T-H Marine HYDRA™ Automatic Bilge Pump is engineered for reliable, high-performance water removal with long-term durability built in. Backed by 4,000 hours of testing, HYDRA delivers dependable operation through its advanced anti-airlock design, ensuring reliable restarts even when air is present in the line. A precision-balanced motor with a 316 stainless steel motor shaft reduces vibration, noise, and corrosion for smooth, long-lasting performance in harsh marine environments.

Designed for simplified service and OEM-friendly installation, HYDRA features a removable nozzle for quick maintenance without disconnecting hoses and a positive-lock strainer base that matches most standard mounting patterns. The integrated Sure-Start™ float switch and programmed start delay prevent false starts and extend pump life, while the external test knob allows fast manual operation checks. Available in 800 GPH and 1100 GPH models and meeting all major ABYC, ISO, and U.S. Coast Guard standards, HYDRA is built for confidence on every outing.
