Top 50 Heavy Duty Boat and Yacht Bilge Pumps

Last Updated: October 17, 2019

Heavy-duty boat and yacht bilge pumps are designed to remove unwanted water from the bilge, keeping the vessel afloat and maximizing its performance. A bilge pump is likely to be the only defense against sinking in the case of a leak, so it’s best to keep one or more in the bilge at all times. Most boats are sold with a stock bilge, but those will wear out over time, especially if they have not been properly maintained.

Heavy-duty bilge pumps are available in automatic and non-automatic variants. Automatic operation requires a bilge pump with an included float switch or a built-in water-sensor. Manual pumps do exist, but they only work for small watercraft. Fishing boats and pleasure yachts need a high-quality bilge pump with a high gallons per hour (GPH) flow rate, and it’s wise to have a backup as well.

Track maintenance and monitor your bilge pump and other marine equipment with durable nameplates and barcode labels from Metalphoto of Cincinnati. The material of choice for more than 50 years, MPC’s Metalphoto® photosensitive anodized aluminum resists fading, corrosion, and abrasion, making it the ideal choice for durable product and process identification in harsh marine environments.

Below we’ve separated automatic and non-automatic bilge pumps and outlined a variety of top-notch pumps with a wide spectrum of heavy-duty GPH flow rates.

SEAFLO 01 Series 3500 GPH

The jump to 3500 GPH is substantial, though at these high numbers the difference may not appear to be much. That 500 GPH step up from the previous model means this pump can discharge an extra 6+ bathtubs of water per hour. That’s quite a lot. You certainly do not want that much extra water sloshing around in your bilge.

Key Features:

  • 3500 GPH flow rate
  • 2-year warranty
  • 12V or 24V compatible

Cost: $130
