Shurflo by Pentair YELLOWTAIL™ 4" Marine Blower - 12 VDC, 215 CFM

The Shurflo by Pentair YELLOWTAIL™ 4" Marine Blower delivers reliable, quiet ventilation for any vessel's critical spaces—bilges, engine compartments, galleys, and heads. Built by Shurflo, a trusted name in marine systems, this 12 VDC unit moves 215 CFM of air with minimal noise, solving the moisture, odor, and heat buildup problems that plague galley and engine spaces after hours on the water. Whether you're running a center console, cruiser, or commercial fishing boat, proper bilge and cabin ventilation separates comfortable passages from dangerous, stale conditions.

This blower features a proprietary six-blade nylon fan design engineered for high-efficiency airflow while maintaining low operating noise—critical when crew needs to communicate or rest below deck. The 4-inch outlet diameter integrates with standard marine ducting, and the compact 6 x 5 x 7-inch footprint fits tight engine rooms where space is at a premium. At just 1.2 pounds, installation adds minimal weight while the 12-volt DC power draw aligns seamlessly with standard battery systems found on virtually every recreational and commercial vessel. The YELLOWTAIL's durable nylon construction resists salt spray and moisture corrosion—essential for sustained reliability in the marine environment.

Boaters and captains who demand fresh, dry compartments—whether drying out a bilge after rough seas or clearing cooking odors from a galley—benefit most from this inline blower's consistent performance. Installation is straightforward: mount the unit inline with existing 4-inch ducting, connect to your 12V electrical bus, and route output through deck vents or through-hull fittings. The YELLOWTAIL pairs with any marine ventilation system using standard 4-inch flex duct, making it an ideal upgrade for older vessels or new builds looking for quiet, efficient cabin air circulation. For anglers, cruisers, and working boats, this Pentair-engineered blower is a practical investment in crew comfort and bilge health.
