🔍 Model Background

The Evinrude Johnson 10 HP Outboard (1973–1978) was designed as a lightweight, portable, and dependable outboard motor ideal for small boats, dinghies, and utility applications. Part of OMC’s (Outboard Marine Corporation) trusted 2-stroke engine lineup, this model offered solid performance in a compact package.

It featured a 2-cylinder, 2-stroke engine with a displacement of approximately 169cc, producing a rated output of 10 horsepower. With a dry weight of around 60–65 lbs, it was easily transportable and manageable by a single person—an advantage for boaters who regularly removed the engine for transport or storage.

The engine used a magneto ignition system for dependable spark delivery, and had a single carburetor for fuel metering. Starting was usually via a manual pull-start, with a tiller handle for throttle and steering control. It was available in short (15") and long (20") shaft lengths to accommodate different transom heights.

This 10 HP model was renowned for its simple maintenance, durability, and quiet operation. It was particularly favored by anglers and small boat owners who needed reliable propulsion in shallow or tight waters where maneuverability was key.

Although eventually overshadowed by the 9.9 HP class due to horsepower restrictions on some lakes and waterways, the 10 HP variant offered a bit more top-end speed for those not bound by such limits. Its robust build and straightforward mechanics continue to make it a popular choice among collectors and vintage outboard enthusiasts today.
