The adjustable boat propeller rotates on a tilting outboard support body, its blades (25) rotatably mounted in a hub on the end of a drive shaft (16) under the action of a pitch-adjusting mechanism (12). The adjusting mechanism is contained inside the hub (11) and ro rotates with it. It can comprise a manually-operated grip (15) at the downstream end of the shaft, acting via a linkage (27-33) on the blade feet (26).
