Mercury - 15 MLH 4-Stroke

2026 Mercury 15 MLH EFI FourStroke Outboard

Portable Power. Proven Reliability. Effortless Control.

Compact, efficient, and ready for adventure — the 2026 Mercury 15 MLH FourStroke delivers dependable performance in a portable package. This 15-horsepower EFI outboard combines modern engineering with lightweight design, making it the perfect match for jon boats, skiffs, and aluminum fishing boats with higher transoms.

Powered by a 333cc inline 2-cylinder, 4-stroke engine with Electronic Fuel Injection (EFI), this model delivers smooth, reliable starting, strong low-end torque, and crisp throttle response—all without the need for a battery. The manual start system is easy to pull, even in cold conditions, while the multi-function tiller handle offers one-handed control of steering, throttle, and shifting.

Weighing only 108 pounds, the 15 MLH is built for easy portability and quick installation. Mercury’s “wishbone” mount system minimizes vibration for a quiet, comfortable ride, while the high-grade marine alloy construction and multi-layer corrosion protection ensure long-lasting durability—even in saltwater environments.
