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

L'invention concerne une casserole (5) d'hélice destinée à une hélice marine (1), laquelle comprend plusieurs pales (2) d'hélice fixées sur un moyeu (3) d'hélice conçu pour être monté sur un arbre porte-hélice (4). Ladite casserole d'hélice (5) est conçue pour venir se monter sur l'arbre porte-hélice (4) et comprend un matériau anodique consommable servant à protéger l'arbre porte-hélice (4) et/ou le moyeu (3) d'hélice contre la corrosion. Cette casserole est en particulier caractérisée en ce qu'elle comprend un cône (6) d'hélice creux formé d'un matériau non anodique, ce cône (6) comprenant au moins une perforation dans sa surface périphérique externe, et un corps (9) rapporté anodique formé dudit matériau anodique consommable, ce corps rapporté (9) étant sensiblement entouré par le cône (9) de casserole creux, et comprenant au moins une protubérance (10) radiale s'avançant au moins partiellement à travers ladite perforation (7) du cône de la casserole (6).
