Description

All-in-one Performance



Intuitive maneuvering for precise control.

Features
  • Electrical support: A high-output alternator keeps batteries charged and fishing electronics humming.
  • 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.
  • Maintain Your Troll: Slow-speed throttle advance has been improved, making it easier for anglers to find and hold their optimal troll speed.
  • 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.
  • 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.
  • Dependable starts and performance: Battery-free Electronic Fuel Injection (EFI) on Mercury 25 - 30hp FourStroke models delivers consistently easy starting, crisp throttle response, increased fuel economy and outstanding overall performance. Mercury 15 and 20hp FourStroke outboards come standard with a three-position choke, eliminating the need for a primer button. Starting is easier and warm-ups are faster!
  • 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.
