VX1800A-X is the model code you should find on a 2022 VX Limited HO, and LIT-18616-04-07 is the Yamaha part number of the manual written for it. Match the code first; the HO sits in the same book as the rest of the VX range, so the sections are organised around codes rather than marketing names.
Yamaha's coverage for this volume reaches from 2021 to 2026 and includes the VX, VX Cruiser, VX Cruiser HO, VX Deluxe, VX Limited, VX-C, and the audio-equipped Cruiser, Deluxe and Limited craft. One book, many hulls, with the differences noted where they exist.
Inside you are working with the factory's own instructions: how components come apart and go back together, what they torque to, how the electrical system is laid out, and the order in which to chase a symptom. That is the whole point of a service manual rather than a general repair guide.
