ADVANCED HIGHLY EFFICIENT MARINE PROPULSION SYSTEM

The Castoldi "Turbodrive 400 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. It is the outcome of specific intensive research and development activities begun in 1985 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 of an instrumented laboratory boat. The Castoldi "Turbodrive 400 H.C." turns out, therefore, as an advanced waterjet unit of the best performance at planing speed,...
