EFI delivers fast, reliable starting and controlled throttle response in all weather
Mercury’s 9.9 EFI ProKicker FourStroke is designed and built to improve every aspect of your time on the water, from starting the engine to changing the oil and everything in between.

TROLL WITH A PRO Mercury Marine FourStroke ProKicker outboards deliver tournament-grade trolling performance in any angling environment.

DEFINING DURABILITY The ProKicker gearcase is engineered to be rugged and durable. With robust gears, bearings and a heavy-duty skeg, the ProKicker is designed to be able to maneuver larger and heavier boats at slow trolling speeds.

MORE THRUST Mercury ProKicker outboards feature a deeper gearcase and a four-blade, high-thrust propeller with lower gear ratio – the perfect setup for trolling and precise troll speed control in all conditions.
