Welcome to Felber Horsepower Solutions!
Our Severe Duty engines are our answer for the big boat needing MAXIMUM THRUST. These are our workhorses aimed at maximum reliability with ALL severe duty components. These engines are aimed at, and developed for SuperWide Blades with maximum prop area and aggressive/flat thrust curves. The ideal engine for a lot of weight, that needs low-speed push. Great for the guide who has to carry an army of people, coolers and decoys, and can’t afford to get hung up!
