These are the most common propellers in use and are found on outboard engines and stern drives.

Bronze propellers are used mainly on competition ski boats, sail boats, commercial fishing boats etc. Blades can be repaired, re-cupped, and re-pitch by up to 2″ up or down. On high performance boats the accuracy and consistency of configuration of the propeller is as important as the balance in preventing vibration and at Castle Marine we pay great attention to these details as well as balancing to an accuracy beyond that required by the manufacturers.
