The Yamaha 140 Jet VG, a powerhouse of the boating world, was a 2-stroke outboard motor renowned for its impressive performance and robust construction. Produced from 1987 to 1995, this engine packed a punch with its 2596cc displacement, making it one of the most powerful outboard jets available at the time. The 140 Jet VG was specifically designed for shallow-water applications, particularly popular among jet boat enthusiasts. Its unique jet drive system, with its specialized impeller and nozzle, allowed it to operate in areas where traditional propellers would get stuck or damaged. This feature made it ideal for navigating shallow rivers, lakes, and coastal areas with rocky bottoms. The design maximized thrust and allowed for quick acceleration and a smooth, responsive ride even in tight spaces. Beyond its performance, the Yamaha 140 Jet VG also boasted durability and longevity, a hallmark of Yamaha's engineering. Its robust construction, with its cast-iron block and forged crankshaft, could withstand the rigors of demanding conditions. The engine's 2-stroke design, though requiring a pre-mix of gasoline and oil, provided unmatched power and efficiency for its time. While the 140 Jet VG is no longer in production, it remains a cherished machine for many boaters, and its legacy lives on through the reputation for reliability and raw power that Yamaha has cultivated over the years. Many enthusiasts still rely on its robust construction and potent performance for a thrilling boating experience, making it a prime example of Yamaha's enduring contributions to the world of outboard motors.
