Features

Features

  • CARB star rating - 3
  • Recommended fuel - 87 octane / up to 10% ethanol

FourStroke Advantage

  • COMFORT: With a balanced powerhead and sophisticated, vibration-dampening cowl design, Mercury FourStroke outboards deliver an exceptionally smooth and quiet ride at any speed.
  • DURABILITY: Premium corrosion-preventive technologies and durable components ensure FourStroke outboards can stand up to the most demanding marine environments.
  • COMPACT DESIGN: Ideal for new engine setups or repowers, the slender width of a Mercury FourStroke outboard fits most transoms, including those with narrow engine wells and tight motor spacing.
  • EFFICIENCY: Explore farther and stay out longer thanks to impressive power-to-weight ratios, intelligent fuel systems and optimized fuel injection (on most models) that maximize performance from every drop of fuel.

FourStroke Performance

  • FLEXIBLE, VERSATILE POWER: A variety of remote and tiller controls, manual and electric start, and power or manual trim (options vary by horsepower) let you set up your engine to match your boat and favorite on-water activities.
  • SMALL BUT MIGHTY: Mercury portable outboards are ideal for powering a range of johnboats, small aluminum fishing boats and rigid inflatables, as well as for secondary power on sailboats.
  • LIGHTER BY DESIGN: Proprietary alloys and advanced cowl materials allow Mercury FourStroke outboards to deliver heavyweight performance in a lightweight package.

Intuitive, Innovative Features

  • ADVANCED TILLER: With a range of adjustments, easy-to-reach controls and the flexibility to be set up for left- or right-handed operation (on select models), Mercury tiller handles put you in complete command of your adventures.
  • EASY PORTABILITY: Simple to install and lightweight, 2.5 to 20hp FourStroke outboards let you bring along the fun wherever it’s needed.
  • CONVENIENT MAINTENANCE: We made maintenance easier with features like a no-spill oil change system, easy-out fuel filter and lifetime maintenance-free valve train
