Model code VX1800A-MA belongs to the 2013 Wave Runner VXR, and the factory manual that documents it is LIT-18616-03-31. Yamaha's coverage there runs 2011 through 2014 and includes the VXS.
The value of a manual like this shows up in the middle of a job rather than at the start. You have something apart, you need to know whether a measured clearance is still within limits, or which of two connectors a wire belongs in, or what the next bolt torques to. Those answers are the whole point.
Also present are the full disassembly and reassembly sequences and the troubleshooting procedures for the engine, fuel, electrical and jet propulsion systems, written as ordered checks so a symptom actually leads somewhere.
Match VX1800A-MA to your hull identification, and keep LIT-18616-03-31 noted for parts cross-referencing.
