🔍 Model Background

The Suzuki 25 HP 2-stroke outboard (1988–2003) was a reliable, lightweight engine built for small boats, inflatables, and utility skiffs that required dependable performance without excess weight or complexity. Offering a solid combination of portable power and simple 2-stroke engineering, it became a favorite for both recreational users and commercial operations alike.

This model featured a durable 2-cylinder 2-stroke powerhead with a carbureted fuel system, CDI ignition, and automatic oil injection for ease of use. It provided quick throttle response, efficient fuel burn, and smooth performance across low to mid-range speeds, making it ideal for quiet lakes, rivers, and inshore waters.

The Suzuki 25 HP was offered in both short and long shaft configurations, with tiller or remote steering options. Its compact design made it easy to install, transport, and service—perfect for camp boats, rentals, or as a backup motor for larger setups.

Produced from 1988 through 2003, the Suzuki 25 HP continues to be appreciated for its rugged build quality, ease of maintenance, and practical all-around utility in the portable outboard class.
