📖 Model Background

The Yamaha SR230, produced from 2003 to 2007, introduced Yamaha’s first 23-ft dual-engine jet boat platform. Featuring twin MR‑1 four-stroke engines—each producing around 140 HP—and paired to twin 155 mm axial-flow jet pumps, the SR230 offered impressive performance while retaining boat-like hull stability. The model was praised for its roomy bowrider layout, comfortable seating for up to 10 (typically 7–8 with gear), and ample storage, making it a favorite for families and recreational boaters. Though entry-level in Yamaha’s 23‑ft line, it stood out for combining sporty acceleration with day-boat practicality and easy maintenance.
