Johnson Pump Ultima Bilge 800 GPH 3/4" Hose Dura Ports

The Johnson Pump Ultima Bilge 800 GPH 3/4" Hose Dura Ports pump is a self-priming centrifugal bilge pump engineered for rapid water removal on recreational and working vessels. This 800-gallon-per-hour pump combines proven Johnson performance with durable Dura Ports construction and 3/4-inch hose connections, making it a go-to choice for boaters who need reliable automatic bilge protection in both freshwater and saltwater environments.

The 800 GPH capacity handles typical bilge accumulation quickly, moving water off the vessel before it becomes a structural or stability concern. The 3/4-inch hose port diameter matches standard through-hull fittings and marine plumbing, simplifying installation and ensuring compatibility with existing bilge system infrastructure. Built with Dura Ports technology for extended service life in corrosive marine environments, this pump resists galvanic and saltwater degradation better than standard cast-iron alternatives, a critical advantage for boats stored in salt air or operating in coastal waters.

This pump is purpose-built for the boater who runs regular passages offshore or operates a working vessel in commercial or professional service. Weekend fishermen, cruisers, and offshore anglers alike benefit from the unattended operation of an automatic bilge system backed by Johnson Pump's reputation for field-proven reliability. Compact footprint allows flexible mounting in tight engine compartments, while the self-priming design eliminates the need for manual repriming after a dry bilge cycle—critical when you're focused on navigation or fishing, not maintenance.

Marine bilge pump selection hinges on flow rate, durability, and ease of installation. The 800 GPH Ultima sits at the sweet spot for vessels in the 25- to 40-foot range—enough capacity to handle minor leaks, heavy condensation, and wave spray without constant cycling, yet compact enough to fit standard installation bays. Johnson's track record in commercial marine service gives confidence that this pump will outlast seasonal use patterns and boat ownership cycles.
