Enhanced features 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
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 includes: 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.
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.
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.
