Mercury Outboards ME25SHS4S
Mercury FourStrokes have long led the pack in clean, quiet, fuel-efficient outboard power, and now the gap grows even wider. We combined innovative engineering with advanced reliability and features to make our outboards run clean, stay quiet, and deliver smooth, responsive performance – all while cutting your fuel and maintenance costs.
The 25 and 30hp FourStrokes have an industry-first battery-less EFI system for easier starting, smooth running, and improved efficiency. That’s not a misprint – they feature electronic fuel injection with no battery.
Mercury FourStroke EFI outboards deliver consistent, easy starts, smooth operation, and reliability. The 25 and 30hp models are the industry's first batteryless EFI outboards.
All portable and mid-range Mercury FourStrokes feature inline designs for inherently smooth operation.
Every 25 and 30hp Mercury Fourstroke utilizes a three-cylinder engine design that delivers better inherent balance than the gutless twin cylinder designs used by some competitive outboards. Mercury’s three cylinder approach results in a smoother and quieter user experience.
Mercury Fourstrokes are designed with a boat load of user-friendly features, such as our multifunction tiller handle. Available on gas assist or power trim models, this tiller handle gives you easy one-handed operation of shifting, stopping, throttle, tilt and starting. More control equals better maneuverability.

PROPELLER NOT INCLUDED ON THIS MODEL ENGINE
Mercury Marine® is a large company with locations, employees, and dealers all around the world. It started back in 1939, when Carl Kiekhaefer (from Mequon Wisconsin) built the first Mercury outboard, the company was pretty small. Carl was a dreamer and tinkerer. He loved the outdoors. He loved engineering. And he loved to go fast. He was a great role model, too.
Mercury Marine has been making world-class outboards and sterndrives for more than 75 years. It has grown into the largest builder of marine propulsion systems in the world. Number one on the water. and didn't get there by sitting still.
Mercury Marine's long history of firsts and foremosts. A history of constant improvements, as they've set and reset the standards for reliable, trouble-free performance; superior power and torque; low emission; and low fuel consumption. And nobody has given boaters more more ways to propel their specific boats, activities, and pursuits reliably, comfortably, and efficiently across the water.
