Detailed description

Designed for manual bilge drainage, the Whale Gusher 10 manual bilge pump (BP3708) is a robust pumping solution suited to demanding marine conditions. This model is part of Whale’s Gusher 10 range and features neoprene seals optimized for bilge water evacuation. It is recommended as a primary bilge pump for boats 12 meters (40 feet) or longer.

Construction and Performance

The Gusher 10 is built with a marine-grade LM6 aluminum alloy body, epoxy-coated for durability in marine environments. Its fittings are in stainless steel. It includes a neoprene diaphragm as standard. This pump can achieve a flow rate of 41 liters (11 US gallons) per minute at 45 strokes per minute, and up to 65 liters (17 US gallons) per minute at 70 strokes per minute. It provides a maximum suction lift of 4 meters (13.5 feet) and a maximum discharge head of 4 meters (13.5 feet). Weighing 2.3 kg (5 lbs), it offers smooth 38 mm (1 1/2 inch) hose connections for simplified plumbing.

Features and Installation

The Whale Gusher 10 pump incorporates high-flow anti-clog valves, eliminating the need for filter maintenance and reducing blockage risks. It is designed for easy installation and maintenance, with quick access to all components. Its self-priming action simplifies operation. The BP3708 model is specifically configured for deck or bulkhead mounting. A removable stainless steel handle with a cord is included for secure storage. The product comes with a 5-year warranty.

Expert opinion

« The Whale Gusher 10: robustness and performance for manual bilge pumping »

The Whale Gusher 10 manual bilge pump (BP3708) is a strategic choice for safety equipment on board, particularly for vessels of 12 meters and above. Its LM6 epoxy-coated aluminum alloy construction provides robustness suited to harsh marine environments, offering a reliable alternative to electric bilge systems, especially in power outages or for specific dewatering needs.

This model, optimized for deck or bulkhead mounting, requires a mounting surface of at least 18mm thickness for secure fastening and must not be screwed directly to the hull. The 38mm (1 1/2") connections facilitate attachment to reinforced hoses, essential to prevent collapse under suction. Installing a Whale strumbox strainer (SB4222/SB5865) is critical to maximize pumping efficiency and minimize residual water levels. A properly installed anti-siphon valve or loop is also mandatory for all discharges below the waterline to prevent backflow.

The Gusher 10 stands out for its large anti-clog valves, reducing maintenance—a significant advantage over pumps requiring frequent filter changes. While designed for stagnant bilge water, its 65 L/min capacity makes it a valuable asset in emergency situations. Note that it is not suitable for flammable liquids or rapid water accumulation in major flooding scenarios. The 5-year warranty reflects the manufacturer’s confidence in this product’s durability.
