Attwood Turbo 4000 Series II In-Line Bilge Blower 1749-4, 12 Volt Water-Resistant, 4 Inch, White

The Attwood 1749-4 is a 4 inch in-line bilge blower from the Turbo 4000 Series II, built to exhaust fumes and moisture from below-deck compartments on 12 volt DC boats. Unlike Attwood's standard turbo blowers, the 1749-4 carries a water-resistant construction, making it suited to installations where occasional contact with moisture is a possibility. It runs on a 12 volt DC power supply, spins at 200 RPM, and draws 6 watts, moving air efficiently through the ducting without placing heavy demand on the boat's electrical system.

The housing is metal, finished in white to blend with common deck and hull colors, and the blower ships with tie straps included for securing ductwork during installation. Because it is an in-line design, it mounts within the ventilation duct run rather than through a bulkhead, making it a straightforward upgrade or replacement for boaters maintaining engine compartment or bilge airflow.
