Shurflo 4" Yellow Tail In-Line Bilge Blower, 220 CFM, 12V Marine Ventilation Fan

The Shurflo 4" Yellow Tail In-Line Bilge Blower delivers efficient ventilation for engine compartments, bilges, galleys, and head closets aboard any boat. Built around a unique six-blade nylon fan, it moves 220 CFM of air while drawing only 5.2 amps, giving strong airflow without placing a heavy load on the electrical system. The heavy-duty ABS fan housing stands up to the marine environment, and a heavy duty shaft seal keeps moisture away from internal components for long-term reliability. A waterproof boot fitted over the motor adds a further layer of protection against water intrusion, and the motor's sealed construction resists corrosion from prolonged exposure to a wet bilge or engine space.

Installation is straightforward thanks to a wider baseplate with oval mounting slots and a longer barb fitting that makes duct connection easier. The blower measures 5.1 inches by 6.4 inches by 4.8 inches and ships with 12 inches of 16 AWG tinned wire leads for hookup. It is compact enough to fit tight compartments while still delivering high-volume airflow. This blower is ISO 9097 marine compliant, NMMA Type Accepted, and meets ISO 8846 Marine and USCG Regulation 183.410 for ignition protection, making it suitable for use in fuel-vapor spaces where ignition-protected equipment is required.
