A turbine for propelling the advance and the operations of boats in three hundred and sixty degrees

摘要

The drive is clamped to the hull of the craft, with the helm (7) turning the hollow tube by a chain-and-sprockets giving the unit twice the movement of the helm. Vertical movement of the helm lever controls the throttle of the motor. The impeller, in the casing (6), is driven by the propulsion motor through the centrifugal clutch (1) and a vertical shaft inside the tube (2) and draws water through the strainer (7). The outer tube turns in mountings (2, 4). The impeller casing (6) turns with the outer tube to direct the propulsion nozzle.
