A fixed pitch propellor (FPP) is typically a single component cast from Bronze. The blades are not removable so if they incur damage, repair is the preferred option. The alternative of propellor replacement is both costly and not short on lead time.
ATZ can support you with inspections and repairs afloat, in dock or even with a dive team. Either way, ATZ can support all your class approved FPP propellor requirements.
