2019 Mercury 15MH 15HP EFI 4-Stroke Outboard Motor

The 2019 Mercury 15MH 15HP EFI Outboard Motor is engineered to provide dependable power, excellent fuel efficiency, and smooth operation for recreational boaters and anglers. Designed with a large displacement powerhead and advanced Electronic Fuel Injection (EFI) technology, this outboard motor produces strong low-end torque, allowing faster acceleration and quick planing even with heavier loads.

This powerful yet lightweight 103-lb portable outboard is ideal for medium-sized jon boats, skiffs, inflatable boats, and small fishing vessels. The EFI system ensures consistent fuel delivery, easier starting, and improved fuel efficiency compared to traditional carbureted engines.

One of the standout innovations of this model is Mercury’s ambidextrous multi-function tiller handle, allowing both left-handed and right-handed operation. The tiller integrates steering, throttle control, gear shifting, and throttle tension adjustment, providing simple one-handed operation for maximum convenience.

The engine also features Mercury’s vibration-reducing “wishbone” mount system, which minimizes engine vibration and enhances overall comfort while operating the boat.

Built using high-grade marine alloy construction, stainless steel components, and zinc-coated internal water passages, this outboard motor is designed to withstand harsh marine environments and is fully saltwater-rated for long-term durability.

Additional features such as manual start, shallow water drive capability, quiet through-propeller exhaust, and easy maintenance components make the Mercury 15MH a dependable and efficient portable outboard motor.

Backed by the trusted engineering of Mercury Marine and a 5-Year Factory Warranty, this outboard motor delivers the power, reliability, and fuel economy modern boaters demand.
