2018 Mercury 15 Hp 15EH Outboard Motor

The 2018 Mercury 15EH is a new 15 HP four-stroke tiller outboard with a 15-inch short shaft and electric start, weighing 121 lb and built in Japan around a 351cc (21.4 cubic inch) powerhead. It suits medium to larger jon boats, skiffs, and inflatables already set up for a short-shaft tiller motor rather than remote controls. What to check before buying Confirm the 15-inch shaft matches your boat's transom height, since a short-shaft motor like this one sits too high on a hull built for a longer shaft. Trim and tilt are manual rather than power-assisted here, and the carbureted fuel system draws from an external 6.6-gallon tank through a quick-connect line rather than an onboard tank. Mercury rates this motor for saltwater use, which matters if it will see time on a coastal boat rather than strictly fresh water. Starting and power Electric start is standard, backed by a 12-volt, 138-watt alternator sized to keep a small starting battery topped off through repeated starts in a day. The 2.15:1 gear ratio and 3-blade aluminum propeller are matched to this powerhead at the factory, and Mercury backs the motor with a three-year warranty. Can I run it on an internal tank instead? It is built around the external 6.6-gallon tank and quick-connect line that ships with the motor. Does it have power trim? No, trim and tilt are adjusted manually on this model.
