Attwood Turbo 4000 Series II In-Line Blower – 12V – White – 1749-4
The Attwood Turbo 4000 Series II In-Line Blower (1749-4) delivers powerful, reliable ventilation for marine engine compartments, bilges, galleys, and enclosed spaces. Designed to exceed marine safety standards, this blower helps remove fumes, moisture, and heat to improve onboard safety and comfort.
Featuring a water-resistant motor and durable housing, the Turbo 4000 Series II is built to perform in harsh marine environments. Its advanced fan blade design provides strong airflow while maintaining quiet operation and low current draw, making it ideal for continuous-duty marine ventilation.
The 12V in-line configuration allows for flexible installation with standard marine ventilation hose, and the clean white housing blends easily into most engine rooms and bilge spaces. Attwood’s trusted engineering ensures long service life and dependable performance for both recreational and commercial vessels.
Key Performance Features
-
High-Volume Airflow: Rated at 230 CFM (Cubic Feet per Minute), providing rapid air exchange for engine compartments to meet USCG safety standards.
-
Patented Fan Blade: Features a five-blade fan with a steep pitch and a "bushing-less" motor design, which reduces noise and increases the life of the unit compared to older blowers.
-
Water-Resistant Housing: The motor and electrical components are sealed within a UV-resistant white plastic housing, protecting the unit from the high-humidity and corrosive environment of a boat’s bilge.
-
Low Power Draw: Draws only 2.5 Amps at 12V, allowing for pre-startup ventilation without putting a significant strain on your cranking battery.
-
Ignition Protected: Specifically designed to be safe for use in gasoline engine compartments (ISO 8846, SAE J1171, and USCG 183.410 compliant).

Installation Instructions
Critical Installation & Safety Tips
-
Direction of Flow: Ensure the arrow on the housing points toward the exhaust vent. The goal is to suck vapors out of the bilge, not blow fresh air in.
-
Ducting: Use 4-inch wire-reinforced ventilation hose. Keep the runs as straight as possible; every bend can reduce your airflow by up to 20%.
-
Mounting: The integrated feet allow for horizontal or vertical mounting. It is recommended to mount the blower as high as possible in the bilge to keep it away from standing water.
-
The 4-Minute Rule: Always run your blower for at least 4 minutes before starting a gasoline engine to ensure all heavier-than-air fuel vapors are cleared.
Improve onboard ventilation and safety with the Attwood Turbo 4000 Series II Water-Resistant In-Line Blower – 1749-4, a trusted solution for dependable marine airflow.
