The 1998-2002 Yamaha 130, 150, 175, and 200HP 2-stroke outboard motors represent a significant era in Yamaha's outboard engine history, known for their powerful performance and durability. These engines were popular choices for a variety of applications, including fishing, recreational boating, and even small commercial vessels. These outboards featured a range of innovative technologies, such as Yamaha's proprietary "OptiMax" direct-injection system, which improved fuel efficiency and reduced emissions. The OptiMax system injected fuel directly into the combustion chamber, leading to more complete combustion and reduced fuel consumption. The lightweight, high-strength aluminum construction of these engines ensured robust performance even in challenging conditions. These models were also praised for their responsive throttles, reliable starting, and smooth operation, further solidifying their reputation for dependability.

The Yamaha 130-200HP 2-stroke outboards were available in various configurations, offering different shaft lengths, gear ratios, and control options to suit various boat types and applications. They were also known for their durability and long lifespan, thanks to their robust construction and meticulous engineering. These engines achieved considerable success, contributing to Yamaha's position as a leading manufacturer of outboard motors. However, as emission regulations tightened in the early 2000s, Yamaha transitioned to four-stroke outboard technology, eventually phasing out this generation of 2-stroke models. Despite their discontinuation, these powerful and efficient outboards continue to be sought after by boating enthusiasts, demonstrating their lasting legacy and enduring appeal.
