Description
CT 550 HYD hydraulic tunnel propeller - a powerful bow propeller for boats up to 42 mCT 550 HYD is a powerful hydraulic tunnel propeller for large boats and vessels up to 42 m. The carefully designed hydrodynamic structure minimises turbulence and maximises thrust, improving manoeuvrability in harbour passages and confined spaces.
The most powerful tunnel propeller in the D400 tunnel class is equipped with MAX POWER designed four-bladed metal propellers. The counter-rotating system ensures maximum efficiency and identical thrust in both left and right directions.

- D400 tunnel class very high thrust
- hydrodynamic frame construction - less turbulence
- Identical thrust left and right
- Excellent manoeuvrability in harbour and at low speeds
- Suitable for professional use and large pleasure craft
All underwater components are shaped with a special hydrodynamic profile, which reduces cavitation and improves the efficiency of the tunnel propeller. This enables smooth and efficient lateral thrust even in heavy vessels.
