Portable Outboard Motor Range |










Innovating the industry with battery-free power.
Mercury FourStrokes have long led the pack in clean, quiet, fuel-efficient outboard power, and now the gap grows even wider. We combined innovative engineering with advanced reliability and features to make our outboards run clean, stay quiet, and deliver smooth, responsive performance – all while cutting your fuel and maintenance costs.
The 25 and 30hp FourStrokes have an industry-first battery-less EFI system for easier starting, smooth running, and improved efficiency. That’s not a misprint – they feature electronic fuel injection with no battery.
RELIABILITY
Consistent Starting
Mercury FourStroke EFI outboards deliver consistent, easy starts, smooth operation, and reliability. The 25 and 30hp models are the industry's first batteryless EFI outboards.
PERFORMANCE
Born To Be Smooth
All portable and mid-range Mercury FourStrokes feature inline designs for inherently smooth operation.
Powerful 3-Cylinder Design
Every 25 and 30hp Mercury Fourstroke utilize a three-cylinder engine design that delivers better inherent balance than the twin cylinder designs used by competitive outboards. Mercury’s three cylinder approach results in a smoother and quieter user experience.
EASE-OF-USE
Fun at your Fingertips
Mercury Fourstrokes are designed with a boat load of user-friendly features, such as our multifunction tiller handle. Available on gas assist or power trim models, this tiller handle gives you easy one-handed operation of shifting, stopping, throttle, tilt and starting. More control equals better maneuverability.
Performance and Power in one convenient package.
Taking the fun with you is one of the great advantages of owning an inflatable boat or small fishing boat. Mercury offers a complete line of extremely light portable FourStroke outboards, with the widest range of models to choose from. So wherever you and your boat go, your Mercury portable FourStroke can also go. The entire line makes operation and portability easy with smart, simple features. Plus, clean, quiet, fuel-efficient FourStroke performance makes them the obvious power of choice.
Key 20hp Features
Large Displacement Design
At 21.4 cubic inches, this engine delivers the strong low-end torque needed to get the hull up on plane, with quicker throttle response and acceleration.
Fingertip Control
Mercury Fourstrokes are designed with a boat load of user-friendly features, such as our multifunction tiller handle. This tiller handle gives you easy one-handed operation of shifting, stopping, throttle, throttle friction, and tilt. More control equals better maneuverability.
Wishbone Mounts
Mercury’s “wishbone” style motor mount system cradles the powerhead and absorbs the torsional rotation of the crankshaft. By isolating and reducing the vibration transmission to your boat, it provides a smooth driving experience.
Long-Lasting Gearcase
Mercury’s 20hp FourStrokes have dual water pickups. So even if you end up in the shallows, your engine will keep its cool and not overheat.
Go anywhere with portable power.
