2026 Mercury 20ELH 4-Stroke Outboard
Lightweight Power. Smooth Performance. Total Control.
The Mercury 20ELH 4S delivers an ideal blend of portable convenience and reliable performance. Compact yet capable, this 20-horsepower, four-stroke outboard is built to power a variety of smaller boats—from aluminum tillers and inflatables to jon and utility boats.
With Electronic Fuel Injection (EFI), the 20ELH offers instant starts, crisp throttle response, and outstanding fuel efficiency across all speeds. The inline 2-cylinder, 333cc SOHC engine delivers quiet, refined power, while the 12-amp alternator ensures dependable charging for onboard electronics.
Weighing just over 110 pounds, this outboard packs impressive power into a portable design. The electric start adds convenience, while a manual backup under the cowl provides peace of mind on the water. The multi-function tiller handle allows for smooth one-handed operation with forward-neutral-reverse shifting built right in, and can be adjusted for both left- or right-handed use.
Engineered for durability and longevity, the 20ELH features saltwater-rated construction, low-copper aluminum alloys, and corrosion-preventive coatings for long-lasting protection. A wishbone mount reduces vibration, and through-propeller exhaust keeps operation quiet and comfortable.
