STOTABSORBERANDE PROPELLER

摘要

A marine propeller mounting arrangement includes a sleeve member (14) for mounting on a propeller shaft (11), a propeller (10) having an inner hub (17) which fits over the sleeve member (14) and a cushion member (16) fitting between the sleeve member (14) and the propeller inner hub (17). The sleeve member (14) includes radially extending projections (26) registering with channels (31) in the hub to positively drive the propeller (10), even in the event of failure of the cushion member (16). The propeller (10) has an outer hub (28) surrounding the inner hub (17) to define an exhaust gas passageway through the propeller (10).
