Details & Inspection Notes
The Suzuki 25 HP DF25ATHL moves to the longer 20-inch shaft and adds power trim and tilt, while keeping tiller steering and push-button electric start. It swings an 11.25 by 10 inch propeller.
Long shaft, tiller control
Going with the longer shaft suits a boat with a deeper transom while still letting the operator run throttle and steering from a tiller handle at the back of the boat rather than from a console. A tiller-mounted switch handles trim and tilt instead of a manual lever, a difference you feel most once the boat is loaded down.
What Suzuki includes
Suzuki equips this engine with an external 6-gallon fuel tank plus its matching line, a propeller sized to this configuration, a basic tool kit, the printed owner's manual, and Suzuki's 3 year factory warranty on the engine itself.
Running character
Electric start is the primary way to get going, and this horsepower class is tuned toward a quiet, fuel-efficient four-stroke character rather than raw speed. Shifting runs forward-neutral-reverse through a front-mounted lever, and a digital ignition module keeps spark timing consistent across the operating range.
Is the trim powered or manual on this one? Powered, controlled by a switch at the tiller. What shaft option is this? The long shaft, built for deeper transoms and heavier loads out on the water.
