THE CASTOLDI TURBODRIVE 284 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 2 8 4 H.C., IS THEREFORE AN ADVANCED TOPPERFORMANCE HIGH SPEED WATERJET. FITTED WITH A SINGLE STAGE AXIAL...
