Incredibly responsive to get you going with little or no prep.
More Thrust: Mercury® ProKicker outboards feature a deeper gearcase and a four-blade, high-thrust propeller with matching gear ratio – the perfect setup for trolling and precise control in all conditions.
Power Tilt: The fastest power tilt in the industry drops a Mercury 9.9 - 15hp ProKicker FourStroke outboard into the water in just five seconds. Exclusive kicker-centering straps align and secure the outboard in full tilt-up position while you’re underway.
Defining Durability: The ProKicker gearcase is engineered to be rugged and durable, with robust gears and bearings and a heavy-duty skeg that’s 55% thicker and twice as strong side-to-side as the previous gearcase.
Command Thrust: Big-time power. With a longer design and bigger components, Mercury Command Thrust was made specifically to deliver the type of power, thrust and control that wider, heavier boats demand. The Command Thrust Difference: 20% larger prop increases control especially at low speeds; Taller gearcase puts the prop deeper, below turbulent water, for improved performance; A low 2.42:1 gear ratio delivers thrust and maneuveraility that big loads demand; Oversized Antiventilation Plate. Oversized design prevents air from being drawn into the prop, which increases efficiency.
Total Single-Handed Tiller Control: Tiller-steered versions feature the exclusive Mercury multifunction tiller that puts shifting, throttle control (with friction for fine-tuned trolling), stopping, tilting and steering in the palm of your hand.
Lightweight: At only 83 pounds, these engines are very portable and improve the performance of lightweight boats.
Convenient and Easy Tilting: Push down on the tiller handle to easily tilt the outboard to any position, made easy with our exclusive ratcheting transom bracket.
Idle Smoothly: The fuel filter on 8, 9.9, 15hp and 20hp Mercury FourStrokes has been moved to keep the carburetor cleaner for reliable starting and smooth idling.
Maintain Your Troll: Slow-speed throttle advance has been improved, making it easier for anglers to find and hold their optimal troll speed.
Richer Idle Air/Fuel Mix: Tiller handle 8, 9.9, 15 and 20hp Mercury FourStrokes have a richer air/fuel mix at idle, making the engines easier to start and providing better idle running quality.
Simplified Start Procedure: Mercury 8 and 9.9 FourStroke outboards come standard with a three-position choke, eliminating the need for a primer button. Starting is easier and warm-ups are faster!
