Mercury 25 HP Tiller Outboard Motor - 2026

Balanced the powerhead to make it smoother and crafted soft - rubber mounts that isolate vibration and direct it away. Spend less time on service and more time on the water with the no - spill oil change system, easy - change gear lube, and lifetime maintenance - free valve train. Electronic Fuel Injection (EFI) provides surefire starts in any weather. The Mercury tiller adapts to you, not the other way around - you can reverse the grip for left - or right - handed throttling and laterally adjust the tiller angle for better leverage and control. With efficient air intake, the powerhead generates impressive torque to move heavy loads with ease. And because the engine works less, it lasts longer, for years of reliable service.

The Mercury 25 HP FourStroke outboard makes light work of your biggest adventures. Quick and compact. Reliable and durable. Efficient and easy to own. FourStroke outboards bring big capabilities to small vessels.
