STANDARD FEATURES

  • 20% larger prop increases control especially at low speeds.
  • A low 2.42:1 gear ratio delivers thrust and maneuveraility that big loads demand.
  • 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.
  • 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.
  • 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.
  • 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.
  • Lightweight. – At only 83 pounds, these engines are very portable and improve the performance of lightweight boats.
  • Maintain Your Troll – Slow-speed throttle advance has been improved, making it easier for anglers to find and hold their optimal troll speed.
  • 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.
  • Oversized Antiventilation Plate. Oversized design prevents air from being drawn into the prop, which increases efficiency.
  • 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.
  • 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!
  • Taller gearcase puts the prop deeper, below turbulent water, for improved performance.
  • The Command Thrust Difference (Blue shaded areas represent prop and gearcase advantages)
  • 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.
