2019 Mercury 15 HP EFI 15MH Outboard Motor

Pull-start simplicity meets fuel injection in the 2019 Mercury 15MH EFI, the lightest engine in this EFI lineup at a dry 103 lb. Dropping electric start trims the weight compared with its EH and ELH EFI siblings, which matters most to owners hand-carrying this motor on and off a small boat.

Engine details

Displacement sits at 333cc, or 20.3 cubic inches, built around a 61 by 57 mm bore and stroke. Thanks to the lighter package, full throttle climbs to a 5700-to-6200-RPM band, noticeably higher than the electric-start versions of this engine, and the tiller handle is built to work from either side rather than favoring one hand.

Coverage

There is no onboard alternator on this manual-start model, so battery charging is not part of this package, and the fuel system draws from the same style of external tank Mercury uses across its 15 HP range. Mercury still backs it with the same five-year warranty term it applies across this EFI lineup.

Does this charge a battery? No, there's no alternator since this is a manual-start model.

How does the RPM range compare to the electric-start EFI version? It runs higher, 5700 to 6200 RPM, since it's lighter without electric start.

Is this carbureted? No, like the rest of this range it runs electronic fuel injection rather than a carburetor.
