2017 Evinrude 15 HP E15RG4 Outboard Motor

Among Evinrude's 2017 carbureted 15 hp outboards, the E15RG4 is the base rope-start setup, riding the shortest shaft in the family at 114.4 lbs. Steering is by tiller, and trim can be manual or power tilt, which keeps the rigging simple for owners who don't need a remote throttle.

What's inside

Bore measures 2.4 in, stroke 2.36 in, out of which this 2-cylinder carbureted engine draws 351 cc, or 21.4 cubic inches, of displacement. At full throttle this block turns 5000 to 6000 rpm on a 2.15:1 final gear, and cooling is by water rather than air.

How it's built

Shifting runs forward, neutral, and reverse off a front-mounted lever, with a carrying handle and a rear holding grip for moving the motor by hand. A single carburetor supplies fuel, routed through the prop exhaust for a quieter note, drawing from a 3.1-gallon external tank. Service relies on Evinrude/Johnson's 5W40 Ultra 4-Stroke oil, 32 ounces per fill, paired with 87-octane gas.
