9.9-25hp ProKicker™

Quiet Performance. Precise Speeds. Complete Control.

Mercury ProKicker™ outboards enable precision boat control, even in the toughest fishing conditions. Quiet, smooth and efficient, they make long hours of trolling more productive – and more enjoyable.

Intuitive, Innovative Features

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.

Custom-Matched Prop
Big boats. Rough waters. No problem. A high-thrust four-blade propeller delivers refined trolling speed authority so you can dial in precise presentations every time.

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.

Power Tilt
No need to lean or strain to stow or deploy the engine. Mercury EFI-equipped ProKicker™ outboards come standard with power tilt.
