All-in-one Performance

Intuitive maneuvering for precise control.

  • Electrical support: A high-output alternator keeps batteries charged and fishing electronics humming.
  • 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
  • Great acceleration / more torque: Compact but powerful, Mercury® 15 - 30hp FourStroke outboards feature extra displacement and outstanding low-end torque that put a boat smartly on plane.
  • 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.
  • 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.
  • 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.
