Details & Inspection Notes
This Suzuki 25 HP outboard, model DF25AES, carries a 15-inch short shaft, tiller steering, push-button electric start and manual trim and tilt, and it ships with the Suzuki 3 year factory warranty.
What arrives with the motor
- A 6-gallon tank for fuel, connected through its own fuel line
- An aluminum propeller already matched to this engine
- A basic tool kit for routine adjustments
- The owner's manual
Running characteristics
This is a four-stroke design tuned for quick starts and steady acceleration rather than top speed, which suits it to running efficiently on a jon boat, skiff or small aluminum hull rather than pushing a heavy load. The tiller handle carries both the throttle and the steering, so speed and direction happen from the same grip at the transom, with no separate console wiring to plan for. Routine upkeep is limited to the basic checks covered in the included owner's manual.
Starting and backup
Electric start handles day-to-day use, and the thru-cowl manual pull cord stays available as a backup if the battery is ever dead. Coverage under the 3 year factory warranty applies to the motor as sold, not to accessories purchased separately.
Common questions
What comes packaged with the motor? The fuel tank and line, propeller, tool kit and owner's manual. What warranty does Suzuki provide? A 3 year factory warranty on the engine.
