Abstract
The invention to which this application relates is to a propeller of the type for use in relation to water vessels and which can be moved between an in-use position in which the blades of the propeller extend outwardly to provide a propulsion force when rotated and, a storage position in which the desire is to minimize the effect of the blades as the vessel moves through the water and in which the blades are held substantially in line with the body of the propeller. The location means which allow the blades to be connected to the body are located within the body and thereby minimize the risk of corrosion and thereby increase the life of the propeller whilst also providing a secure fitment of the blades to the body and allowing ease of movement of the blades between in-use and storage positions.
