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. 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.
Enhanced Features: The Mercury 8 and 9.9hp FourStroke outboards include: New three-position choke and no primer button improve starting, simplify the starting procedure and allow the engine to warm up faster; A richer idle air / fuel mix makes the engine easier to start and provides better idle running quality (tiller handle models); A change to the ignition timing allows fishermen to find and hold optimal troll speed
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.
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 (Blue shaded areas represent prop and gearcase advantages): 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.
Power in the Palm of Your Hand: Tiller models feature the exclusive Mercury multifunction tiller that puts shifting; throttle control (with improved slow-speed throttle advance for optimal trolling); stopping; tilting; 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.
Start Easily, Idle Smoothly: Mercury 8hp to 20hp FourStroke outboards have features that make starting easier, warm-ups faster and idling smoother! The fuel filter on 8hp to 20hp Mercury FourStrokes has been moved to keep the carburetor cleaner; Tiller handle models have a richer air/fuel mix at idle; They also come standard with a three-position choke, eliminating the need for a primer button
