25 HP Mercury 4-STK 2019 Manual Start Short Shaft [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.

RELIABILITY

Consistent Starting

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.

PERFORMANCE

Born To Be Smooth

All portable and mid-range Mercury FourStrokes feature inline designs for inherently smooth operation.

Powerful 3-Cylinder Design

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.

EASE-OF-USE

Fun at your Fingertips

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.
