Whale WD3517S 3.5 GPM 12V High Pressure Washdown Pump Kit with 25 Foot Coiled Hose

The Whale WD3517S is a complete 12V high pressure washdown pump kit built to keep a deck and hull clean without needing a dockside hose bib. At the center of the kit is a high pressure pump that delivers a smooth, constant flow of water at 3.5 gallons per minute and 60 PSI (4.0 bar), enough pressure to cut through salt film, mud, and grime. The pump is designed for use in both fresh and saltwater environments and can run dry without damage, which protects it if the water supply runs low or the strainer momentarily loses prime.

Beyond the pump itself, the kit is assembled to be ready to install and use right away. It includes an inlet strainer and two 1/2 inch barbed connections for plumbing into a water tank or through-hull, plus push-in fittings with a dry coupling valve so the hose can be connected and disconnected without spilling water. A 25 foot coiled hose stores compactly and stretches out to reach around a boat, and it comes with its own storage bag when not in use. At the working end, an adjustable trigger with an ergonomic, soft, non-slip grip lets the user switch between a fine spray and a full jet, and the deck protect nozzle is designed not to mar or damage deck surfaces. The pump runs on 12V DC and calls for a minimum 14 AWG wire size, with a maximum lift of 6 feet. This kit is a self-contained washdown solution rather than a replacement part tied to a specific engine or model, so it fits any boat where a 12V washdown system can be plumbed in.
