🔍 Model Background

The Mercury 50 HP 2-Stroke outboard (1986–2002) was a workhorse in Mercury’s mid-range lineup, built on the brand’s proven 3-cylinder 2-stroke platform. Lightweight, simple, and highly reliable, this engine became a go-to choice for aluminum fishing boats, small center consoles, runabouts, and utility vessels during its production run.

Equipped with carbureted fuel delivery, CD ignition, and oil injection (Precision Blend), the 50 HP model offered strong throttle response, easy cold starts, and dependable performance with minimal maintenance. It was available in both manual and electric start versions, with options for tiller or remote steering, making it adaptable for a wide range of boat types and user preferences.

While eventually phased out due to evolving emissions standards and the rise of EFI and 4-stroke technology, the 50 HP 2-stroke earned a reputation for rugged reliability, mechanical simplicity, and excellent power-to-weight ratio. Many are still in use today, especially in freshwater applications, with abundant aftermarket parts and service support available.
