The Suzuki DF25A is a 490 cc, three-cylinder 4-stroke with battery-less multi-point EFI and Lean Burn Control, the same powerhead as the DF30A. Suzuki lists the manual-start short shaft at 136.6 lb and the electric-start short shaft at 143 lb. It is the smallest Suzuki available with full power trim and tilt, which is why it is so common on aluminum fishing boats, pontoons and utility boats.
