Sea-Dog Hand Bilge Pump 18" x 24"

The Sea-Dog Hand Bilge Pump 18" x 24" (Model 503124-1) is a manual bilge pump designed for small boats without electrical systems or as emergency backup for larger vessels when engine-driven pumps fail. This compact, lightweight pump eliminates dependency on shore power and delivers 6–13 GPM, making it practical for weekend fishermen and serious boaters operating in remote waters where electrical systems may not be reliable or available.

Constructed from UV-resistant injection-molded nylon, the pump resists degradation from prolonged sun exposure and saltwater spray—critical for coastal operations and offshore fishing environments. The removable foot valve simplifies maintenance and field cleaning without tools or dock access. Removable hose connections with storage clips keep the pump stowed safely without kinks or damage. Important: hoses must be screwed on securely; pushing hoses onto fittings causes leaks and loss of priming. The 1.45-pound weight and compact 8" × 4" × 22" dimensions allow easy stowage in cabin lockers, lazarettes, or emergency kits even on space-constrained craft.

This hand pump serves as mandatory safety equipment on boats operating far from assistance, during extended cruising, or in waters where electrical systems are prone to failure from corrosion or impact. Backup bilge capacity is essential when water intrusion occurs—mechanical reliability under pressure makes manual pumps indispensable for serious mariners. The Sea-Dog brand is recognized in the marine industry for durable, field-proven hardware built to function consistently in harsh saltwater conditions.

Hand bilge pumps are a Class II emergency system under USCG guidelines for vessels operating offshore or beyond help zones. Unlike electric pumps, mechanical bilge capacity requires no battery, engine, or electrical troubleshooting—only physical effort. The 6–13 GPM range suits hulls up to approximately 25 feet, though flow varies with operator effort and intake water conditions.
