A new casting technique makes the Chopper II propeller more durable than ever. The new Chopper II, an improved version of the original Chopper propeller, works well on heavier boats that need bow lift. The enhanced bow lift reduces drag, increasing the efficiency of the boat and improving overall performance. The Chopper II permits higher engine mounting on the transom for greater speed. Designed to run 50+ MPH. Equipped with a rubber hub.
