The Mercury 25EH is a compact, lightweight four-stroke outboard motor designed for small boats such as jon boats, skiffs, inflatables, and small fishing vessels up to 14-16 feet. Featuring a 15-inch short shaft, it weighs 138 lbs, making it one of the lightest in its 25 HP class. The 500cc (30.5 cubic inch) inline three-cylinder engine with Electronic Fuel Injection (EFI) delivers strong low-end torque for quick planing and a full throttle range of 5000-6000 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, 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 25EH is ideal for worry-free boating.

8 reviews for Mercury 25hp EFI 15″ Shaft | 25EH
+ FREE GIFT
The 25EH transformed my lightweight aluminum boat. Instant electric starts via EFI, smooth inline-3 power pushes 19 mph loaded, and it’s so fuel-efficient I forget to refuel. The 15″ shaft handles chop without cavitation, quiet enough for chatting on the water. Lightweight design means easy swaps—Mercury quality for everyday escapes!
This Mercury 25EH EFI shines on my creek skiff. Electric start fires instantly without a battery, and the 500cc engine planes me fast even with tackle aboard. Trolled for hours on minimal fuel, topping 21 mph solo. The short shaft avoids snags, and it’s whisper-quiet for spotting wildlife. Lightweight and durable—zero fuss after 40 hours!
Workhorse for my utility pram—the 25EH EFI’s short shaft and manual tilt suit tight ramps, electric start saves time, and torque hauls gear without strain. Sips fuel during patrols, tops 22 mph clean. Runs cool and quiet in brackish spots. At 138 lbs, handling is simple—reliable, versatile, and ready for anything!
Really solid on my tiller-steered jon boat—the 15″ shaft fits low-freeboard hulls perfectly, and EFI ensures crisp response from idle. Great low-end torque for gear-heavy trips, runs quiet all day. Fuel economy beats my old 2-stroke hands down. Only minor gripe is manual tilt takes a little muscle in mud, but performance and ease of start make it a winner.
Upgraded to this 25hp EFI for my small pram, and the electric start is a game-changer—no pulling cords in the rain. The inline-3 delivers quick planing and fuel sipping efficiency, about 6 mpg cruising. Pushes 19 mph loaded, with minimal noise for early morning outings. At this weight, storage is a breeze. Mercury’s reliability in a compact package—love it!
