Mercury 25EH FourStroke EFI 15″ Outboard Motor

The Mercury 25EH FourStroke EFI 15″ Outboard Motor is a compact, lightweight, and fuel-efficient portable outboard designed for anglers, recreational boaters, and utility applications. Powered by Mercury’s dependable 526 cc inline 3-cylinder SOHC 4-stroke engine, the 25EH delivers excellent low-end torque, smooth acceleration, and quiet operation while maintaining one of the best power-to-weight ratios in its class. Its Electronic Fuel Injection (EFI) system provides instant starting, crisp throttle response, and improved fuel economy without requiring a manual choke.

Designed with a 15-inch (Short Shaft), electric start, and tiller steering, the Mercury 25EH is ideal for jon boats, aluminum fishing boats, inflatables, skiffs, utility boats, and small workboats. The lightweight three-cylinder design offers smoother operation than many twin-cylinder competitors, while through-propeller exhaust, manual trim with shallow-water drive, and corrosion-resistant construction ensure dependable performance in both freshwater and saltwater environments.

Whether you’re fishing your favorite lake, navigating rivers, or powering a small commercial craft, the Mercury 25EH FourStroke delivers the performance, reliability, and efficiency that Mercury Marine is known for.
