Mercury 25 and 30hp FourStroke outboards make light work of your biggest adventures. Quick and compact. Reliable and durable. Efficient and easy to own.
FourStroke outboards bring big capabilities to small vessels. With efficient air intake, the powerhead generates impressive torque to move heavy loads with ease. And because the engine works less, it lasts longer, for years of reliable service. Pound for pound, these outboards are big performers. They’re the lightest 3-cylinder outboards in their class.
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.
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.
Electronic Fuel Injection
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 Tiller with remote control
Configure your outboard to fit your boat and your needs, with remote controls for steering from the helm or a nearly 23-inch tiller that’s perfect for precision handling. The tiller adjusts for left- or right-handed driving and features a down-angle stop that holds it at the right height for comfortable steering while seated or standing. Throttle friction can also be adjusted to help hold speed.
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 CTA. A major advantage for small vessels and heavy loads.
Speed and Acceleration
FourStroke outboards are optimised 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.
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.
A series of Black Max propellers, designed specifically for the 25hp FourStroke and offered in 1-inch pitch increments, lets you choose the perfect prop to optimise performance with your boat.
