🔍 Model Background

The Suzuki 140 HP 2-stroke outboard (1988–2003) was a versatile V4 engine developed to deliver strong performance and responsive acceleration for a wide range of boating applications. Positioned between the lighter inline engines and the larger V6 models, the 140 HP offered smooth power delivery and reduced weight—making it a great fit for bay boats, sportfishing rigs, and performance-oriented recreational hulls.

Powered by a carbureted V4 2-stroke engine, this model featured CDI ignition, automatic oil injection, and manual or electric start configurations. It was engineered for boaters who needed quick planing ability and solid midrange torque without stepping up to a V6.

The Suzuki 140 HP outboard earned a reputation for being reliable, fuel-efficient, and easy to maintain, with broad compatibility for both single- and twin-engine setups. Its straightforward mechanical design and wide availability of parts made it a favorite among DIY boaters and mechanics alike.

Produced from 1988 through 2003, the Suzuki 140 HP remains a respected choice for those who value lightweight V4 performance, proven 2-stroke technology, and all-around versatility.
