Product catalog summary

Overview: The Castoldi Turbodrive 490 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.

Benefits:

Performance: Achieves higher top speeds and better fuel economy than fixed pitch propellers and competitor waterjets. It maintains full thrust regardless of boat speed changes.
Safety: Features no open rotating blades or hull appendages, providing excellent emergency stop capabilities and resistance to debris and grounding.
Practicality: Offers corrosion resistance, ease of installation, minimal maintenance, and reduced weight and magnetic signature.
Comfort: Reduces vibration and internal noise.
Maneuverability: Provides outstanding control at all speeds, including sideways movement without bow thrusters.

Technical Specifications:

Input Flange: Supports up to 250 mm diameter drive shaft flange.
Impeller: Three blades, single stage, axial flow with a diameter of 490 mm.
Gearbox: Integrated with 20 gear wheel-ratios.
Weight: Unit dry weight is 890 kg; hydraulic components weigh 54 kg.
Materials: Constructed from high-grade stainless steel, titanium, bronze aluminum alloy, and high-strength marine aluminum alloy.
Protection: Features hard anodizing treatment, special paint layers, and cathodic protection by zinc anodes.

Unique Features: Includes a multi-ratio gearbox, hydraulic multi-disc clutch, debris screen grid, and a packaged control system for enhanced maneuvering capabilities.

Conclusion: The Turbodrive 490 H.C. is a result of extensive research and development, offering a robust, efficient, and versatile propulsion solution for marine vessels.

THE CASTOLDI TURBODRIVE 490 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 4 9 0 H.C., IS THEREFORE AN ADVANCED TOPPERFORMANCE HIGH SPEED WATERJET. FITTED WITH A SINGLE STAGE AXIAL...
