Details & Inspection Notes
At 2.5 HP, Suzuki's DF2.5S4 is a single-cylinder, four-stroke outboard with its fuel tank built into the housing, a manual pull cord for starting, and a short shaft, sized for dinghies, tenders, and small inflatables rather than full-size boats.
Who this fits
With the tank built in rather than external, there's nothing extra to route on deck, trading some running time between fills for a cleaner, simpler setup, which suits tenders where space is tight. There's no reverse gear on this motor; turning the whole unit 360 degrees handles backward maneuvering instead. A compression-reduction system is built in to keep the pull-start light.
What to check before buying
Displacement runs 260 cc from a single cylinder, using splash lubrication rather than a pump-driven system, and tilt adjusts by hand across three trim positions. Corrosion protection covers the aluminum parts of this motor, and it's cleared for use in both fresh and salt water, shipping with a 3-blade aluminum propeller, printed manual, and tool kit under Suzuki's 5-year manufacturer warranty.
Common questions
Does this motor have a reverse gear? No; rotating the motor a full turn is used for reverse instead.
Is an external fuel tank needed? No, the tank is built into the motor itself.
A built-in carrying handle makes it easy to move this motor between a car trunk and a tender without extra hardware.
