2018 Mercury 15 Hp 15MLH Outboard Motor

Mercury's 2018 15MLH weighs in at 118 lb and pairs a pull-start, 15 HP four-stroke engine with the longer of the two shaft lengths in this manual-start family. A tiller handle and manual trim keep the controls simple, and the powerhead is the same 21.4-cubic-inch design used across Mercury's 15 HP range.

What to check before buying

This unit is built with the long shaft option, so confirm that length against your boat's transom height before ordering rather than assuming the shorter version in this lineup will fit. An alternator kit for battery charging is available as a separate, optional purchase rather than standard equipment, and full throttle on this carbureted engine falls between 5400 and 5600 RPM.

Build and coverage

A 2.15:1 gearcase turns a 3-blade aluminum propeller sized for this powerhead, and saltwater-rated construction covers the water passages and fittings. Mercury backs this engine with a three-year warranty; confirm the exact shaft length with us before ordering if your transom measurement is close to the line.

Is this the short-shaft or long-shaft version? The long-shaft version.

Can I add battery charging later? Yes, an alternator kit is available as a separate purchase.

Is steering handled by a tiller or remote controls? A tiller handle, with forward-neutral-reverse shifting built directly into the grip rather than a separate shift lever.
