TX1900A-BAG is the model code for the 2025 AR190, and Yamaha documents it in service manual LIT-18616-04-43.
The SX190 is covered by the same part number, and the manual holds for the 2024, 2025 and 2026 model years. The two 19-foot boats share their mechanical package, so the factory wrote one set of procedures and noted where the models differ.
Inside are the periodic maintenance tables, engine service from scheduled checks through disassembly, jet propulsion unit procedures, hull and deck hardware, steering and control adjustment, and the electrical chapter with complete wiring diagrams. Torque values, clearances and service limits appear with the work they govern, and troubleshooting is arranged by the symptom an owner would report.
On a smaller boat that often gets owner maintenance, the schedule and the diagrams are the sections that see the most use. Confirm TX1900A-BAG before ordering parts.
