🔍 Model Background

The Mercury 15 HP 2-stroke outboard (1986–2003) was one of the most popular and widely used portable engines of its time, known for its simplicity, durability, and strong performance in a lightweight package. Built on a 246cc 2-cylinder crossflow engine block, this model offered excellent power-to-weight ratio — making it a favorite for anglers, campers, and utility boat operators.

Featuring a carbureted fuel system, CDI ignition, and manual or electric start options, the 15 HP 2-stroke delivered quick acceleration and reliable operation across a range of conditions. It was well-suited for jon boats, inflatables, dinghies, and small aluminum fishing boats, and could be easily transported due to its compact size and manageable weight.

Simple to maintain and easy to service, the 1986–2003 Mercury 15 HP 2-stroke became a benchmark in small outboard reliability. Its long production run and shared parts with 9.9 HP models made it an enduring favorite among boaters seeking dependable, no-frills performance in a portable 2-stroke platform.
