Johnson Pump In-Line Bilge Blowers - 3" and 4" Inlet/Outlet, 12V

The Johnson Pump In-Line Bilge Blower moves fresh air through your engine compartment and ventilates dangerous fuel vapors before they can build up, a critical piece of safety equipment on any gas-powered boat. Built with a high-impact, anti-shock ABS plastic body and a stainless steel shaft, this in-line blower installs directly into standard ducting using either flange mount or flex mount hardware, giving you flexibility to fit it into tight compartments. A double ball bearing motor is rated for continuous duty, so it can run for extended periods without overheating, and the entire unit runs on a standard 12 volt DC circuit. Available in two sizes to match different hose diameters and airflow needs, this blower line covers everything from smaller runabouts to larger center consoles that need higher CFM ventilation.

Sizes & Options

Choose the 3 inch inlet/outlet version (158 CFM) for smaller compartments and boats already running 3 inch ducting, or step up to the 4 inch inlet/outlet version (240 CFM) for larger bilges or when you need faster air exchange. Match the blower size to your existing hose diameter to avoid needing a reducer, and size up the CFM rating if your compartment is larger or holds more fuel vapor risk.
