📖 Model Background

The Yamaha 250 HP V6 2‑stroke outboard (model codes S250TXRV/VX/VW) was produced from 1997 through 2003 as a heavyweight performer in Yamaha’s powerful 2‑stroke V6 line. Powered by a 3.13 L (3,130 cc) loop‑charged V6 engine with electronic fuel injection (EFI in later years) and CDI ignition, it delivered strong mid- and top-end power. The engine weighs around 229 kg (505 lb) and was noted for its bulletproof reliability, ease of tuning, and instant response - traits praised in Yamaha owner forums and service manuals.

Designed for offshore and commercial use, this V6 featured durable EFI (OX66) fuel control in later years, power trim & tilt, and a beefy gearcase capable of handling high torque. Known as one of the most reliable consumer-grade V6 two-strokes ever made, it remained a trusted choice for performance boats, charter operations, and fishermen throughout its run.
