🔍 Model Background

The Evinrude Johnson 15 HP Outboard (1973–1978) was a compact and reliable 2-stroke engine that became a favorite among small boat owners, anglers, and utility craft operators. It shared many design elements with its 9.9 HP sibling, with differences primarily in carburetion and porting to deliver more power while maintaining a lightweight, portable profile.

This model featured a 2-cylinder, 2-stroke engine with a displacement of around 246cc, and produced 15 horsepower at the prop. Known for its excellent power-to-weight ratio and durability, it provided strong acceleration and top-end performance on lightweight hulls, including jon boats, inflatables, and small aluminum fishing boats.

The 15 HP outboard was typically configured with manual pull-start and tiller steering, and came in both short (15") and long (20") shaft versions. With a dry weight of approximately 70–75 lbs, it remained highly portable, suitable for use as a kicker motor or easily removed for storage.

Owners appreciated the engine’s rugged construction, simple maintenance, and availability of parts. Features like a magneto ignition system and single carburetor made the motor reliable in a variety of conditions, especially in remote or saltwater environments where simplicity was key.

The Evinrude Johnson 15 HP from this era continues to be praised for its balance of power, reliability, and ease of use—earning a reputation as one of the most dependable small outboards ever produced.
