Sea Sense Thru-Hull Pump 800GPH

The Sea Sense Thru-Hull Pump 800GPH is a 12-volt DC bilge pump purpose-built for boat owners who need reliable water removal without fuss or downtime. Whether you're managing routine bilge discharge, emergency dewatering, or liveaboard comfort, this pump moves 800 gallons per hour—enough capacity for small to mid-sized vessels where fast response matters. It's the kind of straightforward, no-nonsense marine gear that earns trust through years of consistent performance on the water.

What sets this pump apart for overlanders and boaters alike is its practical design. The 3/4" outlet fits standard marine plumbing, and you get both straight and angled thru-hull fittings in the box, so installation adapts to your hull layout without hunting for adapters. The ignition-protected motor meets marine safety standards, and the pump handles running dry—a crucial feature if your bilge doesn't stay flooded—so accidental air-locks won't burn it out. That's real peace of mind on long cruises or in rough conditions.

This is not a fancy pump. It's a workhorse: 12-volt, 800 GPH, built to start and keep running when you need it. If you're fitting a boat or pontoon with straightforward, proven bilge capacity and you want hardware that won't surprise you with failure, the Sea Sense Thru-Hull delivers.
