Mercury 25 HP EFI Fourstroke

Mercury 25 and 30hp FourStroke outboards make 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.

Exceptionally Smooth and Quiet

We balanced the powerhead to make it smoother and crafted soft-rubber mounts that isolate vibration and direct it away. Whether you’re fishing in a quiet cove or having a conversation, you’ll enjoy every minute on the water.

Easy to Maintain

Spend less time on service and more time on the water with our no-spill oil change system, easy-change gear lube and lifetime maintenance-free valve train.

Electronic Fuel Injection

Electronic fuel injection (EFI) provides surefire starts in any weather. On manual-start engines, battery-free EFI delivers efficient, reliable performance without a bulky cranking battery.

Advanced Mercury Tiller

The Mercury tiller adapts to you, not the other way around. You can reverse the grip for left- or right-handled throttling and laterally adjust the tiller angle for better leverage and control.

Available Power Tilt and Trim

Easy to stow, easy to control. Power tilt and trim, available for 25 and 30hp FourStroke outboards, lets you adjust the running attitude with the push of a CTA. A major advantage for small vessels and heavy loads.

FourStroke Advantage

Power to Move More: 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.

Remote or Tiller Controls: Configure your outboard to fit your boat and your needs, with remote controls for steering from the helm or a nearly 23-inch tiller that’s perfect for precision handling.

Comfortable Setting: The tiller adjusts for left- or right-handed driving and features a down-angle stop that holds it at the right height for comfortable steering while seated or standing. Throttle friction can also be adjusted to help hold speed.

Custom-Matched Prop: A series of Black Max propellers, designed specifically for the 25 and 30hp FourStroke family and offered in 1-inch pitch increments, lets you choose the perfect prop to optimise performance with your boat.
