The Mercury 20ELHPT is a compact, lightweight four-stroke outboard motor designed for small to medium boats such as aluminum fishing boats, pontoons, inflatables, and small cruisers up to 14-16 feet. Featuring a 20-inch long shaft, it weighs 127 lbs, making it one of the most portable in its 20 HP class. The 327cc (20.0 cubic inch) inline two-cylinder engine with Electronic Fuel Injection (EFI) delivers strong low-end torque for quick planing and a full throttle range of 5500-6000 RPM. Its innovative multi-function tiller handle, adjustable 18 degrees port or starboard and reversible for left- or right-hand use, offers exceptional control and comfort. The motor features a 3.2-gallon external fuel tank, an electric start system for effortless ignition, power tilt for easy adjustments, and low-vibration wishbone mounts for smooth operation. Built for durability in freshwater and saltwater, it uses low-copper aluminum alloys, stainless steel components, and a multi-layered priming and painting process for superior corrosion resistance. With reliable starting, instant throttle response, and fuel efficiency, the 20ELHPT is ideal for worry-free boating.

7 reviews for Mercury 20hp EFI 20″ Shaft | 20ELHPT
This Mercury 20hp EFI is a trolling champ on my bass boat. Starts instantly with no fuss, and the 333cc powerhead planes me quick even overloaded. Fuel efficiency is top-notch—saved 25% over my old carb model—while topping 22 mph clean. The lightweight build and quiet 4-stroke vibe make all-day trips a joy. Zero issues after 30 hours!
Mounted the 20hp EFI on my inflatable tender, and it transforms it into a real boat. EFI reliability for instant starts, great fuel sipping during drifts, and solid 18 mph top end loaded. The 20″ shaft fits low transoms perfectly. Slight con: prop guard could be optional for rocks, but performance and quiet run make it a winner.
The 20ELHPT powers my creek skiff like a dream—lightweight for easy swaps, battery-free EFI for hassle-free launches, and torque that laughs at currents. Trolled trout on minimal gas, hits 21 mph bursts without strain. Ultra-quiet inline-3 keeps wildlife undisturbed. Versatile, durable—Mercury nailed the portable 20hp!
Upgraded to this 20hp EFI for my aluminum skiff, and it’s been flawless. Battery-free EFI means no extra weight or charging worries, and the inline-3 delivers quick planing with minimal fuel burn—about 6 mpg cruising. Pushes 19 mph loaded, trolls down to 1.5 mph precisely. Super quiet for early outings, and at this price, it’s a steal. Mercury reliability shines!
Ideal portable for my 15-foot lake boat—the 20ELHPT’s EFI adapts to loads for smooth power, manual start in any weather, and efficiency stretches every tank. Strong torque for chop, pushes 20 mph with three aboard. Whisper-quiet operation lets me hear the sonar clearly. At 115 lbs, trailering is effortless—best small EFI out there!
