Mercury 20hp EFI Tiller 4-Stroke Outboards

Mercury 20hp EFI Tiller 4-Stroke Outboards

Mercury Marine's advanced 4-stroke outboard engine delivers 40% better fuel efficiency than comparable 2-stroke models, providing exceptional value and long-term savings. These clean-running engines exceed California Air Resources Board (CARB) 3-Star emissions standards and deliver 91% lower emissions than traditional 2-stroke outboards, making them among the most environmentally friendly options on the market.

Engineered for anglers, recreational boaters, and commercial operators, this 4-stroke outboard combines ultra-quiet, smoke-free operation with smooth idling and reliable performance. The battery-free EFI system ensures fast, dependable starting and instant throttle response, while the lightweight design improves acceleration, top speed, and handling. A decompression system and electronic CD ignition provide easy starts and reliable operation in all conditions. One-stage over-rev protection and a low oil pressure warning system add extra peace of mind on the water.

Available in multiple horsepower ranges from 2.5 to 20hp, the exclusive multifunction tiller handle (on 8hp and higher models) puts shift, steering, throttle, throttle friction, and stop controls at your fingertips for convenient one-hand operation. Choose from manual-tilt, gas-assist, or power-trim options to match your boating needs. The manual trim system with 5 to 6 trim positions, plus a shallow-water drive, adapts to varying water conditions. All models include a propeller.
