2019 Mercury 15 HP EFI 15EH Outboard Motor

At 111 lb, the 2019 Mercury 15EH EFI undercuts the carbureted 15EH models in this lineup on weight while keeping the same 15-inch short shaft and tiller setup. Electronic fuel injection in place of a carburetor is the headline change on this model, aimed at owners who want easier cold starts without fiddling with a choke.

Engine details

Displacement works out to 333cc, or 20.3 cubic inches, smaller than the carbureted 15EH's powerhead, with a 61 by 57 mm bore and stroke. Full throttle falls in the 5000 to 6000 RPM range, and the same 6.6-gallon portable tank used elsewhere in this lineup supplies fuel, connected by a quick-connect fitting instead of a built-in reservoir.

Power and coverage

A 138-watt alternator supports the electric start and a 2.15:1 gearcase turns the propeller, with oil changes calling for roughly 1000 ml. Mercury's warranty on this engine runs five years; if you need the exact displacement confirmed for your specific unit, check with us before ordering.

Is this carbureted or fuel injected? Electronic fuel injection, which sets this EH variant apart from the carbureted version in the same lineup.

What's the dry weight? 111 lb, lighter than the carbureted 15EH.

Is steering handled by a tiller? Yes, this model keeps the tiller handle rather than remote controls, with the shift lever built into the grip.
