Stump-Jumper Propeller Information

Overview


The Stump-Jumper propeller is a top of the line performer for the backwater enthusiast. Bill's Engineering spent years designing, testing and perfecting the newest of mud motor propellers with a process which provides clone-like production in every propeller; same size, same shape, same thickness and perfectly balanced. The 9 ¼ x 7 Stump-Jumper propeller drives a motor sized 18 horsepower and up, the 6 ¾ x 5 is ideal for motors 5.5hp and up. Poured of 420 stainless steel with thicker blades for longer wear, and hardened to Rockwell 43 for durability and toughness. Deep cupped blades provide real mud biting performance and weed shedding qualities to ensure you keep moving forward. Standard ¾ 10 NC size threads fit any other mud motor. Field testing has proven boats plained off faster using the Stump-Jumper propeller.
