High Thrust
Description
Our 996-cc 60-hp High Thrust outboard is a powerful addition to a day spent on the pontoon or houseboat. Its SOHC four-cylinder design, composite long-track intake system, large lower unit and high gear ratio mean it packs a lot of thrust in a compact design.
Our 996-cc 50-hp High Thrust outboard has the extra measure of muscle you need for pushing heavy loads, such as a loaded pontoon. Its SOHC four-cylinder design, composite long-track intake system, large lower unit and high gear ratio deliver powerful punch in a compact design.
25 HPOur 432-cc 25-hp High Thrust outboard boasts the best power-to-weight ratio of any high-thrust 25 horsepower outboard on the water. It features no-battery-required Electronic Fuel Injection and electric and manual start on all models. With 20- and 25-inch shaft lengths and our Variable Trolling RPM Switch (VTS®) for slower trolling than in-gear idle, it’s a flexible fishing machine.
Our 212-cc 9.9-hp High Thrust outboard is the perfect kicker for flats and multi-species boats. Available in both 20- and 25-inch shaft lengths, it can power boats with 25-inch transoms that venture into deeper, rougher waters. At just over 100 pounds, it offers a surprising combination of high-thrust power and portability.
