Turbodrive 340 H.C.

Product catalog summary

Overview: The Castoldi Turbodrive 340 H.C. is an advanced marine propulsion system designed for high efficiency and performance in the 25 to 60 knot speed range. It offers superior speed, fuel economy, and maneuverability compared to traditional propulsion systems.

Performance: The system provides fast acceleration, maintains full thrust regardless of boat drag changes, and offers higher top speeds than fixed pitch propellers and competitor waterjets. It is designed for optimal performance with both gasoline and diesel engines, supporting up to 625 kW output.

Safety: The Turbodrive 340 H.C. enhances safety by eliminating open rotating blades and appendages under the hull. It features an emergency crash stop capability and is resistant to floating debris and unexpected grounding.

Practicality: The system is corrosion-resistant, easy to install, and requires minimal maintenance. It operates effectively in shallow waters and has a reduced magnetic signature, contributing to longer engine life.

Comfort: The propulsion system minimizes vibration and internal noise, enhancing onboard comfort.

Maneuverability: It offers outstanding maneuverability at all speeds, including zero-speed docking with 360° thrust availability. In multiple installations, vessels can move sideways without bow thrusters.

Technical Specifications: The Turbodrive 340 H.C. features a three-blade, single-stage axial flow impeller with a diameter of 337 mm. It includes an integrated multi-ratio gearbox, a hydraulic multi-disc disconnecting clutch, and a debris screen grid. The unit's dry weight is 307 kg, with additional hydraulic components weighing 50 kg.

Materials and Protection: Key components are made from high-grade materials such as AISI 316 stainless steel, titanium, and aluminum alloys. The unit is protected by hard anodizing, special paint layers, and zinc anodes for cathodic protection.

Conclusion: The Castoldi Turbodrive 340 H.C. is a result of extensive research and development, offering a unique and efficient solution for marine propulsion with advanced features and robust construction.

THE CASTOLDI TURBODRIVE 340 H.C. IS NOT ONLY THE RESULT OF ALL THE EXPERIENCE GAINED SINCE 1962 THROUGH THE SUPPLY AND INSTALLATION OF MORE THAN 40.000 WATERJETS WORLDWIDE. IT IS THE OUTCOME OF SPECIFIC INTENSIVE RESEARCH AND DEVELOPMENT ACTIVITIES AIMED AT FURTHER IMPROVING THE HIGH EFFICIENCY OF CASTOLDI WATERJETS. THIS GOAL WAS PURSUED THROUGH SELF-PROPULSION TRIALS (USING 24 TRUE-SCALE MODELS) PERFORMED BY MEANS OF AN INSTRUMENTED LABORATORY BOAT. AS A RESULT, THE CASTOLDI T URBODRIV E 3 4 0 H.C., IS THEREFORE AN ADVANCED TOPPERFORMANCE HIGH SPEED WATERJET. FITTED WITH A SINGLE STAGE AXIAL...
