2025 Yamaha SX190 Service and Repair Manual
Hull code TX1900B-BAP identifies the 2025 SX190, and LIT-18616-04-43 is the Yamaha service manual that goes with it.
The book is shared with the AR190 and runs from 2024 through 2026. Those two boats are built on the same platform, so the factory documented them side by side rather than in separate volumes.
Work covered includes the engine and jet pump, hull and deck hardware, fuel and cooling systems and the boat's electrical circuits. Each section gives the removal and reinstallation order, the inspection measurements with their limits, and the torque figures. Wiring diagrams are complete, and the troubleshooting tables are arranged by the symptom an owner would describe.
Before you buy, match TX1900B-BAP to the plate on your own boat. Codes are the fitment check that model names alone cannot give you.
