A propeller spinner ( 5 ) for a marine propeller ( 1 ) having multiple propeller blades ( 2 ) attached to a propeller hub ( 3 ) that is adapted for attachment to a propeller shaft ( 4 ) and includes a sacrificial anodic material for protecting the propeller shaft ( 4 ) and/or propeller hub ( 3 ) from corrosion. There is included a hollow spinner cone ( 6 ) made of a non-anodic material and the spinner cone ( 6 ) has at least one perforation in its outer peripheral surface. An anodic insert body ( 9 ) that is made of the sacrificial anodic material constitutes an insert body ( 9 ) that is substantially contained within the hollow spinner cone ( 6 ). The insert body ( 9 ) has at least one radical protrusion ( 10 ) extending at least partially through said perforation ( 7 ) in the spinner cone ( 6 ). |
