engine details

FourStroke 25 EFI

Delivers consistent, easy starting, crisp throttle response, increased fuel economy, and outstanding overall performance. Great for aluminum tiller, aluminum console, jon, utility, and fish & ski boats.


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

Port side or starboard, you pick the mounting location, and the tiller adapts to you. Its reversible throttle grip can be configured for control with either hand, while lateral adjustments ensure a convenient steering angle.

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



Speed and Acceleration

FourStroke outboards are optimized for reliable performance and fun in all seasons. The 500cc, single-overhead cam design delivers the fastest speed and acceleration among 3-cylinder, 30hp outboards.

Lightweight & Compact

Pound for pound, these outboards are big performers. They’re among the lightest 3-cylinder outboards in their class.

Powerful Alternator

Even at low speeds, the alternator delivers powerful battery-charging output to keep onboard electronics humming. And there are no belts or bearings to maintain.



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.

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.

Remote or Tiller Controls: 

CConfigure 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.

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 optimize performance with your boat.



SmartCraft. The Power To Do More.

SmartCraft®, now available for 25hp ProKicker™ outboards, is a full suite of digital technologies, fully integrated and totally coordinated. Gauges, sensors, vessel systems, computer-controlled features – one total package, one high level of control. Make your boating experience easier, safer and a lot more enjoyable.
