Intuitive, Innovative Features
Exceptionally Smooth and Quiet
Advanced Mercury Tiller
The Mercury tiller adapts to you, not the other way around. You can reverse the grip for left- or right-handled throttling and laterally adjust the tiller angle for better leverage and control.
Easy to Maintain
Spend less time on service and more time on the water with our no-spill oil change system, easy-change gear lube and lifetime maintenance-free valve train.
Available Power Tilt and Trim
Easy to stow, easy to control. Power tilt and trim, available for 25 and 30hp FourStroke outboards, lets you adjust the running attitude with the push of a button. A major advantage for small vessels and heavy loads.
Electronic Fuel Injection (EFI)
Electronic fuel injection (EFI) provides surefire starts in any weather. On manual-start engines, battery-free EFI delivers efficient, reliable performance without a bulky cranking battery.
Fourstroke Performance
Speed and Acceleration
FourStroke outboards are optimized for reliable performance and fun in all seasons. The 500cc, single-overhead cam design delivers the fastest speed and acceleration among 3-cylinder, 30hp outboards.
Lightweight & Compact
Pound for pound, these outboards are big performers. They’re the lightest 3-cylinder outboards in their class.
Powerful Alternator
Even at low speeds, the 17-amp alternator delivers powerful battery-charging output to keep onboard electronics humming. And there are no belts or bearings to maintain.
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.
