The Suzuki DF25A is an ultralight 25 HP four-stroke outboard engine that brings multiple innovations to the compact class. Sharing the same 490 cc 3-cylinder engine as the DF30A, this motor delivers reliable power with an exceptionally low weight (~62–65 kg, depending on model) and a battery-less EFI fuel system. The DF25A is a class leader in lightness and economy – its Lean Burn technology ensures minimal fuel consumption, and a direct air intake design boosts power output.

Ultralight & Compact: The DF25A is among the lightest 25HP motors available. It’s easy to install/remove and ideal for portable setups, foldable boats, and small RIBs where weight is critical.
Battery-Less EFI: The engine starts quickly and reliably every time, even without a battery, thanks to its advanced fuel injection system. This eliminates the weight and hassle of a battery, especially valuable on inflatable boats.
Lean Burn Advantage: The DF25A automatically adjusts to a lean air-fuel mix at cruise – delivering noticeably lower fuel consumption than older carbureted 25HP engines. Enjoy more hours of runtime on a single tank of gas.
Offset Crank & Roller Rockers: An offset crankshaft reduces piston friction, and the inclusion of roller rocker arms (a first in this class) cuts losses in the valve train. The result is smoother operation, less vibration, and higher mechanical efficiency.
LED Monitoring Panel: Like the DF30A, the DF25A features a trio of LED indicators that monitor key parameters (temperature, oil pressure, check engine). This gives the user peace of mind that the motor is running optimally and provides a warning in case of any issue.
Recommended Use: Ideal for small inflatable dinghies (about 2.5–3.5+ m), jon boats and other small fishing boats, or as a kicker/backup motor. The DF25A is powerful enough to propel small craft loaded with 2–3 people, and it’s excellent for camping and remote outings where the engine’s light weight and low fuel use are crucial.

The Suzuki DF25A is designed with mobility and efficiency in mind. As the “little brother” to the DF30A, this engine inherits all of its strengths but targets boaters who have limited space or weight capacity on their boat or simply don’t need more than 25HP. Recommended uses and advantages include:

Perfect for Inflatables and Tenders: The DF25A shines as the main engine for small RIB inflatables, dinghies, canoes with transom mounts, and other compact craft. The absence of a battery means the entire boat can remain as light and simple as possible – ideal for quick launching or carrying the boat by hand to the water’s edge.
Camping and Exploration: For adventurers hitting various waterways, the DF25A offers a combination of small size and just-enough power to reach remote spots. It can be easily strapped to a camper or carried over rough terrain to a mountain lake. Its frugal fuel usage means you don’t have to haul large amounts of fuel with you.
Sporty Feel in a Small Package: At 25HP, the DF25A still delivers impressive pep on the right boats – it can quickly accelerate lightweight RIBs with two people aboard and get them on plane. It’s also great for gentle watersports like pulling small kids’ tubes or a kneeboard, where safety and control trump raw power.
Reliable for Long Fishing Days: Many anglers use the DF25A for drifting and trolling, where steady, quiet low-speed operation is key. Thanks to the LED alerts, they can easily monitor if everything is okay with the engine at a glance, removing guesswork. And with Lean Burn, they can spend all day creeping along a river or lake without noticeably denting the fuel supply.
Great Value Investment: With its simplified maintenance (no carburetor to clean, no belt to change) and proven durability, the DF25A pays off over time. This is an engine that can retain high resale value due to the strong reputation of the series. For clubs or educational programs looking for a reliable small outboard for training purposes, the DF25A is often a top pick.
