Whale Compac 50 Manual Bilge Pump Thru Deck/Bulkhead Mount

The Whale Compac 50 Manual Bilge Pump Thru Deck/Bulkhead Mount is purpose-built for boaters and anglers operating in tight quarters where traditional pump installations simply won't work. After years on the water, any seasoned captain knows that bilge management is non-negotiable—standing water breeds corrosion, mold, and worse. This compact manual pump solves the space constraint problem that plagues smaller vessels, center consoles, and heavily-rigged fishing boats where every cubic inch of bilge space is already spoken for.

Built by Whale Marine—a trusted name in marine fluid systems—the Compac 50 features a low-profile, compact design engineered to fit into confined bilge spaces without sacrificing reliability. The thru-deck/bulkhead mount configuration allows for direct installation through hull or cabin sole, eliminating the need for awkward suction hose routing or additional structural modifications. Manual operation means zero electrical draw and zero dependency on batteries or switches—a critical safety advantage during extended offshore runs or in rough conditions when redundancy matters most. The 50-series sizing delivers adequate displacement for emergency bilge evacuation on vessels up to approximately 25 feet, depending on leak rate and sea state.

This pump is ideal for retrofits on older sportfish boats, practical for skiffs and shallow-draft vessels where space behind sole compartments is minimal, and essential for cruising sailboats carrying redundant dewatering systems. The thru-deck installation method provides immediate access and visibility—a tactical advantage when you're troubleshooting or priming. At 3 lbs with compact dimensions of 7 x 6 x 12 inches, the Whale Compac 50 fits where others cannot, making it the go-to choice for boaters who refuse to compromise on safety in confined spaces.
