Exceptionally Smooth and QuietWe 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. |
Easy to MaintainSpend 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. |
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. |
Advanced Mercury TillerThe 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. |
Available Power Tilt and TrimEasy 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. |
Speed and AccelerationFourStroke 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 & CompactPound for pound, these outboards are big performers. They’re the lightest 3-cylinder outboards in their class. |
Powerful AlternatorEven at low speeds, the alternator delivers powerful battery-charging output to keep onboard electronics humming. And there are no belts or bearings to maintain. |
