🔍 Model Background

The Suzuki 120 HP 2-stroke outboard (1988–2003) was a versatile V4 engine designed for boaters seeking dependable midrange horsepower in a lightweight and easy-to-service platform. Positioned just below the 125 and 140 HP models, the 120 HP offered smooth performance, fuel efficiency, and balanced power delivery for a wide range of recreational boats.

This engine featured a carbureted V4 2-stroke powerhead with CDI ignition and automatic oil injection, delivering reliable starts, consistent midrange torque, and simplified maintenance. Its compact design made it an excellent match for bay boats, center consoles, runabouts, and dual-engine setups where weight and transom capacity were key considerations.

The Suzuki 120 HP was favored by boaters who wanted near-125 HP performance in a slightly lighter package. Its durable construction and long production run made it easy to service, with strong OEM and aftermarket parts availability.

Produced from 1988 through 2003, the Suzuki 120 HP outboard is still appreciated by classic outboard enthusiasts who value proven 2-stroke reliability, solid V4 performance, and practical rigging flexibility.
