The QS Seamaster 185 mm stern tunnel deflectors are designed to improve water channeling in the boat’s rear area. This accessory is essential for maximizing the efficiency of propellers or thrusters installed in tunnels, helping to achieve a more direct flow, less turbulence, and an overall improvement in maneuverability.
Technical Characteristics
- Tunnel diameter: 185 mm.
- Made of corrosion-resistant material (exact material to be confirmed: usually composite or marine stainless steel).
- Suitable for stern propeller or thruster tunnels.
Advantages
- Improves water flow channeling through the tunnel.
- Reduces cavitation and turbulence.
- Optimizes thrust during maneuvers.
Applications
- Boats with stern tunnel propellers.
- Installations of side thrusters or dynamic positioning systems.
Installation Tips
- Confirm compatibility with tunnel diameter and model.
- Screw or glue the deflector following the manufacturer's specifications.
- Regularly check for obstructions or dirt buildup.
Maintenance
- Regular cleaning with fresh water after navigation.
- Perform visual inspections before and after each season.
- Replace in case of cracks or structural damage.
