Gasoline engine compartments can accumulate fuel vapors in the bilge. A marine blower ventilates the space before ignition — a core ABYC safety practice.
Why Blowers Matter
SEAFLO in-line blowers move 130–270 CFM at under 45 dB, pulling vapors through ducting to a deck vent.
Hose Size & CFM
Match blower inlet/outlet to hose diameter (3" or 4"). Larger hose reduces restriction and improves effective CFM on long duct runs.
Mounting Tips
Mount the in-line blower in accessible ducting, oriented for airflow arrow direction. Use marine-grade hose clamps and support long duct spans.
Pre-Start Checklist
Run the blower for at least four minutes before engine start on gasoline inboards and sterndrives. Label switches clearly at the helm.
