The Suzuki DF25AS5 is a technologically advanced four-stroke outboard motor designed for small to medium boats, including jon boats, skiffs, inflatables, and small fishing vessels up to 14-16 feet. Featuring a 15-inch short shaft, it weighs 136 lbs, making it one of the lightest in its 25 HP class. The 489cc (29.8 cubic inch) three-cylinder engine with battery-less Electronic Fuel Injection (EFI) and Lean Burn technology delivers quick starts, strong acceleration, and superior fuel efficiency, running on 87-octane fuel. Its manual start system with an Easy Start Recoil Starter requires minimal pull strength, and the multi-function tiller handle offers one-touch steering and throttle control for precise handling. The DF25AS5 is equipped with a revised engine cover and air cleaner for smoother, cooler airflow, enhancing power output from a compact displacement. Built for durability in freshwater and saltwater, it features Suzuki’s Anti-Corrosion Finish, sacrificial anodes, and a freshwater flush port. With low noise, minimal vibration, and eco-friendly operation, this motor is ideal for portable, efficient boating.

6 reviews for Suzuki 25HP 15″ Shaft | DF25AS5
motor works well but throttle felt a bit stiff initially took some time to adjust but after that it’s been reliable and efficient
best small motor i’ve had so far quiet and responsive perfect for fishing trips and easy to carry around got it at a solid price too so it was a great deal
runs smoothly and starts right up every time the build quality feels solid and it handles well in choppy water i’d definitely recommend this suzuki
this suzuki 25hp is super reliable starts easy and runs really smooth love the compact design and the 15″ shaft fits perfectly on my boat
good motor with decent power and fuel efficiency took a little time to get used to but once i did it’s been running great overall very happy with the purchase
