🔍 Model Background

The Evinrude Johnson 50 HP Outboard (1973–1989) was a versatile and long-running 2-stroke motor designed for light to mid-sized boats, including fishing skiffs, pontoons, and small runabouts. Known for its durability, smooth performance, and widespread parts availability, it became a mainstay in recreational boating across North America and beyond.

Powered by a 2-cylinder inline 2-stroke engine with a displacement around 521cc, the 50 HP model delivered reliable mid-range power with responsive acceleration. Over the years, Evinrude and Johnson refined the engine with features like loop charging, improved port timing, and upgraded carburetion for better efficiency and smoother operation.

Starting systems included both manual and electric start options, with ignition provided by Magneto or CDI systems depending on the model year. It was offered in both tiller and remote steering versions, making it adaptable to a wide range of hull types and user needs.

The outboard featured a robust gearcase and an efficient water-cooling system, suitable for both freshwater and moderate saltwater use. Its mechanical simplicity and shared parts across models made it easy to maintain and repair, contributing to its popularity among DIY boaters.

With a production span lasting over 15 years, the 50 HP outboard became one of the most trusted and enduring models in Evinrude and Johnson's lineup, valued for its balance of power, portability, and reliability.
