15 HP Outboard Motors: Real Planing Power for 14 ft Boats
Fifteen horsepower turns a slow crossing into a quick hop and still weighs about what a 9.9 does. All five major brands, compared honestly.
15 HP outboard motors are two-cylinder four-strokes weighing roughly 95 to 115 lb that plane 12 to 16 ft aluminum boats, skiffs and larger inflatables with two or three people aboard.
Nora, Jess and the outgoing tide
Nora and Jess loved the oyster bar at the mouth of their tidal river. Getting home was the problem. Their 14-foot skiff wore an old 8 HP, and on an outgoing tide the trip back upstream turned into a long, loud, one-mile-an-hour argument with the current.
They upgraded to a 15 HP four-stroke with electric start. The skiff popped onto plane with both of them and a bushel of oysters, and the run home dropped from fifty minutes to twelve. Jess still checks the tide table, but now only to decide how long they can stay.

At full throttle a 15 HP four-stroke typically burns around 1.5 gallons per hour, and much less at cruise. A 3 to 6 gallon tank covers most day trips.
Is a 15 HP too heavy to carry?
At roughly 95 to 115 lb it is a two-person lift for most people. Owners usually leave it on the boat and trailer it.
