The Stump Jumper weighs in at just 62 lbs! That’s nearly 10% less than our closest competitor!1 But lightweight doesn’t mean light duty! Stump-Jumper frames are built with tubular construction and fully jig welded to exacting standards. Stump-Jumper also features our proprietary E-Z setup direct drive coupler, our direct drive coupler eliminates power robbing U-joints. This means that the propeller’s shaft and propeller see almost virtually all the power the engine makes. Speaking of power, the Stump-Jumper with the 6.5 or 7 hp air cooled engines.
The engine’s power is transmitted to the propeller via a Stump-Jumper exclusive design propeller driveshaft. The propeller’s driveshaft is supported by a low maintenance sealed bearing design that does not require daily greasing. Connected to our propeller’s driveshaft is our own Stump-Jumper 6 ¾ x 5 15-5 stainless steel propeller. We’ve tested and refined this propeller specifically for our design to provide maximum performance and heat treated to a Rockwell 40 hardness for the perfect balance of durability and wear resistance.
The Stump-Jumper is perfect for anyone who needs a lightweight highly capable mud motor. Perfect for flat bottom boats, lay out boats, square stern canoes or any boat with a short transom, the Stump-Jumper at just 62 lbs. Once you get to the water Stump-Jumper is easily attached in seconds with our quick disconnect transom mount. The Stump-Jumper also features a multi-position handle that can be reversed to aid in transport or storage.
Using the Stump-Jumper is a pleasant and hassle free experience. The transom mount balances the weight of the motor assembly making raising and lowering the engine a breeze, and the ergonomic tiller handle adjusts to multiple positions to accommodate different boats and drivers. The powerful engine and propeller design cuts through weeds, muck and sand with ease allowing you to focus on where you want to go and enjoy the outdoors rather than worrying if you’ll make it.
