The Attwood Marine Sahara S750 is a 12V automatic bilge pump built for larger recreational boats, specifically vessels 20 feet and over with sleeping accommodations where an automatic-switch pump is required. It moves 750 gallons per hour at open flow and 625 gallons per hour at a 3.3-foot head, with the float switch integrated into the housing so the pump cycles on without crew attention. Everything ships in one compact package, including the pump, 36 inches of wire, seals, strainer, and the mercury-free switch. For boaters comparing options across our bilge pump lineup, the S750 covers the mid-range flow most cabin boats need.
Construction is where the Sahara earns its place in saltwater service. The motor uses a permanent magnet design with a 316 stainless steel shaft, a high-impact glass-filled polyester impeller, and steel-reinforced seals, all rated as saltwater corrosion resistant. It draws 1.5 amps at 12V DC and connects through a 3/4-inch hose outlet, with 36 inches of 16-gauge caulked and tinned copper wire included for the run to your panel. The float design uses non-restrictive movement and a larger filter area to resist clogging, and water flows freely around the housing to keep the motor cool. A test knob lets you confirm operation by hand, and one-handed removal makes disassembly and cleaning quick. Dimensions run 5-1/2 inches long by 3-1/4 inches wide by 4 inches tall, not counting the hose nipple.
Most boaters install the Sahara as a primary or secondary automatic bilge pump in the lowest point of the bilge, wired through a panel switch for manual override. Its 750-gallon-per-hour rating suits cabin boats and cruisers where a hand pump alone won't keep up. If you're building out a complete bilge setup, pair it with a backup float switch for redundancy and run new discharge hose sized to the 3/4-inch outlet. Attwood Marine backs the S750 with a 3-year warranty. Questions on flow rates or wiring? Our team works marine plumbing every day and can point you to the right pump for your hull.
The Sahara S750 is rated at 750 gallons per hour at open flow and 625 gallons per hour at a 3.3-foot head, per manufacturer specifications. Open-flow numbers reflect ideal conditions, so the head-height rating is the more realistic figure once discharge hose and lift are factored into your installation.
Yes. The float switch is built into the housing, so the pump cycles on when bilge water rises and shuts off when it drops. A test knob lets you confirm operation by hand. Many boaters still wire it through a panel switch for manual override and to add a backup float switch for redundancy.
The pump has a 3/4-inch hose outlet and ships with 36 inches of 16-gauge caulked and tinned copper wire. It draws 1.5 amps at 12V DC. Size your discharge hose to the 3/4-inch outlet and run dedicated wiring to your panel for the cleanest installation.
It's built for it. The motor uses a 316 stainless steel shaft, a glass-filled polyester impeller, and steel-reinforced seals, all rated saltwater corrosion resistant. Free water flow around the housing keeps the motor cool during extended cycles, which matters in salt environments where heat and corrosion shorten pump life.
An automatic-switch bilge pump is required on vessels 20 feet and over with sleeping accommodations, and it's a sensible convenience on smaller boats too. The S750 is sized for that larger recreational class. Backed by a 3-year Attwood Marine warranty, it covers the mid-range flow most cabin boats need.
