Attwood Heavy-Duty Bilge Pump – 1700 GPH | Model 47304
When water gets in, you need a pump that won't quit. The Attwood 47304 Heavy-Duty Bilge Pump is built for boats that work hard — delivering 1700 gallons per hour of reliable pumping capacity with a motor engineered for extreme duty cycles. Whether you're dealing with a slow seep or a serious ingress situation, this pump is designed to keep up.
Attwood engineered the 47304 with premium-grade internals: high-quality bearings, brushes, alloys, and magnets that outlast standard bilge pumps in demanding conditions. The stainless steel motor shaft resists corrosion, and the advanced resin exterior holds up against engine oil, aggressive detergents, and hose plasticizers — the real-world chemicals found in any engine compartment.

- Chemical-resistant resin exterior — stands up to engine oil, detergents, and hose plasticizers

- CE rated

Parts Desk Insights
The Attwood 47304 is the right choice when you need serious pumping capacity in a compact, durable package — ideal for larger cruisers, sportfishers, and any vessel where bilge water accumulation is a real concern. The swivel base and rotating outlet make it one of the easier high-capacity pumps to fit into awkward bilge configurations. If you need automatic float switch operation, pair this pump with a compatible bilge switch. For higher output, see the Attwood Heavy-Duty 2000 GPH Bilge Pump. For a self-contained automatic option at lower flow rates, the Attwood Sahara MK2 800 GPH is a popular fit for smaller bilges.
