Yamaha issued this service manual under part number LIT-18616-04-43, and it is the reference the factory wrote for the 2026 AR190 jet boat built as hull code TX1900A-CAG.
One book covers the 2024 through 2026 model years, and the SX190 is documented alongside the AR190 because the two share their running gear. That is worth knowing before ordering: if the plate on your boat reads TX1900A-CAG, or if you are working on a sister SX190 from any of those years, the procedures inside apply.
What the manual sets out
- Step-by-step removal, inspection and reassembly work, in the order Yamaha specifies
- Torque figures and clearance limits for the fasteners and assemblies you disturb
- Wiring diagrams and circuit checks for tracing an electrical fault
- Troubleshooting charts that start from the symptom rather than the part
Match the part number and the code before you begin, and the specifications you read will be the right ones.
