Abstract
A marine propeller including a hub rotatable about a longitudinal axis and having a plurality of blades extending outwardly from the hub. Each of the propeller blades includes a fixed propeller blade stem and a removable cup extension. The cup extension defines the trailing edge of each propeller blade and is removably mounted to the propeller blade stem. The cup extensions can selectively be removed from the blade stems and new cup extensions attached in order to modify the amount of cupping included on the propeller.
