Look for VX1900A-C on the hull if you are servicing a 2026 VX Limited HO with the audio package. The corresponding Yamaha service manual is LIT-18616-04-38.
Yamaha kept this volume's scope narrow: model years 2024 through 2026, and only the Cruiser HO, the Cruiser HO w/ audio and this Limited HO w/ audio. Those craft share enough hardware that one set of procedures genuinely serves all three, and where they differ the book says so.
What that gets you at the workbench is the factory's numbers and the factory's order of operations. Torque figures instead of guesses. Service clearances instead of feel. Wiring diagrams with real circuit identification instead of tracing harness by hand. And troubleshooting written as a sequence, so a symptom leads somewhere rather than in circles. Cite LIT-18616-04-38 when cross-checking against a dealer parts listing, and confirm the code before you turn a fastener.
