For the 2003 AR210, coded LST1200D-B, Yamaha published LIT-18616-SB-02.
The volume is a single model year but several boats: the LS2000, the LST1200-B and LST1200A-B, and the LX210 share it with the AR210. These hulls used common drive and engine hardware, which is why one book answers for all of them, and why the specification tables are organised around codes rather than names.
The service material follows the factory order of work. Engine disassembly comes with measurement points, wear limits and torque figures. Jet pump procedures cover impeller clearance and wear ring service, along with the steering nozzle and reverse gate. Fuel and cooling systems, bilge, hull and deck fittings each have their sections. The electrical chapter includes full wiring diagrams and test values, and the troubleshooting tables are written from symptoms back to causes.
