🔍 Model Background

The Evinrude Johnson 115 HP Outboard (1973–1985) was a workhorse of the V4 two-stroke outboard family, known for its dependable performance, simple design, and versatility. Positioned as a mid-to-high power option, it was widely used on a variety of boats—from fishing rigs to recreational runabouts—during its production run.

Featuring a 1.6-liter (99.6 cubic inch) V4 crossflow two-stroke engine, the 115 HP delivered solid torque, reliable top-end speed, and straightforward maintenance. Earlier models used a points ignition system, which evolved into a CD ignition system in later years, enhancing starting reliability and combustion efficiency.

The engine offered manual or electric start, remote steering, and optional power trim and tilt depending on configuration. With dual carburetors and a mechanical fuel pump, it provided smooth and predictable throttle response, especially in mid-range cruising.

Built to endure heavy use, the 115 HP V4 gained a reputation for ruggedness, parts availability, and ease of service. Its design remained relatively unchanged across the production span, making it a favorite for owners who valued mechanical simplicity over modern complexity.

Even decades later, many of these engines remain on the water thanks to their strong build quality, widespread support, and loyal following in the boating community.
