The Mercury 15ELH 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 20-inch long shaft, it weighs 114 lbs, making it one of the lightest in its 15 HP class. The 333cc (20.3 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 5700-6200 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 15ELH is ideal for worry-free boating.

6 reviews for Mercury 15hp EFI 20″ Shaft | 15ELH
Upgraded to this Mercury EFI from a carbureted 9.9, and wow—the difference in easy starting and smoothness is huge. Pushes my bass boat to 20 mph solo, trolls down to 1.5 mph precisely. Super efficient, low vibes, and at 115 lbs, it’s a breeze to handle. Ideal for weekend warriors like me!
This 15hp EFI is a gem on my inflatable dinghy. Instant throttle response thanks to the EFI, and fuel sipping is impressive—got a full afternoon of cruising on half a tank. The 20″ shaft fits great, and it’s whisper-quiet for sneaking up on redfish. Weighs next to nothing compared to my old 2-stroke. Mercury quality at its best!
The 15hp 15ELH is perfect for my hybrid kayak setup. EFI means no fuss starts, and it’s so light I can swap it between boats easily. Quiet enough not to spook wildlife, and fuel economy lets me explore farther without worry. Hit 17 mph loaded—great power for the size. Couldn’t ask for more!
Installed the Mercury 15ELH on my small pram, and it’s transformed my river runs. The electronic injection delivers consistent power, and it’s amazingly fuel-thrifty—saved me trips to the station. Runs cool and quiet all day. Slight con: electric start drain on small batteries, but manual backup works fine. Highly satisfied!
Picked up the Mercury 15ELH EFI for my 14-foot jon boat, and it’s been a total winner. The EFI starts right up every time—no battery needed, even on foggy mornings. Super lightweight at 115 lbs, easy to mount solo. Trolled for trout all day on under 2 gallons, and it hits 18 mph with two people. Quiet and smooth—perfect for peaceful fishing trips!
