Overview
The Attwood Marine 1733-4 is a 12V in-line bilge blower for 3 inch ventilation hose, used to move air through engine compartments, bilges, galleys, and heads where moisture is part of the environment.
This is the water-resistant version in white. It is rated at 145 CFM open flow at 13.6 V, with 100 CFM in a typical installed system, and it draws about 3.1 amps with a 4-amp fuse. The blower is ignition protected and mounts in-line with built-in feet, so it can be fitted vertically or horizontally when space around the duct run is limited.
Key features
- Fits 3 inch I.D. ventilation hose for common bilge blower replacement work
- 12V DC operation with 145 CFM open flow and 100 CFM in-system airflow
- Water-resistant construction with a motor cap that seals the wires and motor
- Ignition-protected housing for ventilated spaces that can collect fuel vapors
- Built-in mounting feet support vertical or horizontal installation
- Nickel-plated motor can helps resist corrosion in damp marine spaces
- Tabs at the intake and exhaust help keep hose and clamp seated
- 16-gauge tinned copper wire leads and two tie straps are included
Installation and fit
This blower installs in a 3 inch duct run and mounts with #10 fasteners. The in-line body works well in transom, under-deck, and other confined spaces where hose routing leaves little room around the blower itself.
It is a sensible match for owners replacing an older 3 inch blower on a 12V system or adding forced ventilation to enclosed spaces on board. Water-resistant construction suits damp locations, but this model should not be installed where it will sit in direct contact with water or other liquids.
Electrical and system integration
For buyers checking system fit, this blower is for 12V DC wiring and a 3 inch ventilation layout. The published airflow figure is measured at 13.6 V, so real output on board will depend on hose length, bends, vents, and other restrictions in the run.
That makes it a good fit for boats that already use 3 inch ducting and need a like-for-like replacement without changing hose size, mounting direction, or basic electrical setup.
