Attwood Marine 1494A1 Venturi Vent Black Louver Hull Mount

The Attwood Marine 1494A1 Venturi Vent is a hull-mounted louver vent designed for reliable boat ventilation in both intake and exhaust applications. This black finished vent features a clean, contemporary louver design that complements modern boat aesthetics while providing effective airflow for engine compartments and enclosed spaces.

Key Features:

• Corrosion-resistant ABS plastic construction that will not discolor or fade
• Modern louver design provides efficient airflow while keeping water out
• Designed for installation from either inside or outside the hull
• Compatible with 3" or 4" I.D. ventilation systems
• Meets ABYC H-2 cross-sectional area requirements for marine ventilation
• Sized for installation even on highly contoured deck surfaces
• Installs with standard #8 screws (not included)

This vent requires a separate collector box for complete installation: use Attwood 1341 collector box for 3" systems or 1342 for 4" systems. The ventilation hose (not included) twists into the bottom of the collector box to form a raised water barrier. Black finish complements dark-colored boats and provides a durable, professional appearance.
