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
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 alternator delivers powerful battery-charging output to keep onboard electronics humming. And there are no belts or bearings to maintain.
Intuitive, Innovative Features
EXCEPTIONALLY SMOOTH AND QUIET: We balanced the powerhead to make it smoother and crafted soft-rubber mounts that isolate vibration and direct it away. Whether you’re fishing in a quiet cove or having a conversation, you’ll enjoy every minute on the water.
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.
Warranty & Maintenance
WARRANTY COVERAGE: Mercury makes world-class marine products backed by world-class warranties.
MAINTENANCE: At Mercury, we make maintenance easy. Learn more about how to keep your Mercury products performing at their peak.
