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.
