ADVANCED HIGH EFFICIENT MARINE PROPULSION SYSTEM

The Castoldi “Turbodrive 340 H.C.” is not only what is led to all the experiences gained since 1955 with the supply of more than 30.000 water jet units all around the world. TECHNICAL SPECIFICATIONS INPUT FLANGE: SUITS UP TO 7,08˝ (180 MM) DIAMETER DRIVE SHAFT FLANGE. IMPELLER TYPE: THREE BLADES, SINGLE STAGE, AXIAL FLOW. IMPELLER DIAMETER: 337 MM - AT THE INLET. It is the outcome of intensive research and development activities aimed to further improve the high efficiency of the Castoldi waterjet drives and pursued trough self propulsion trials (of really No. 24 scale models) performed by means...
