Code FX1900A-BA marks the 2025 build of the audio-equipped FX Cruiser HO. Yamaha covers it in LIT-18616-04-36, the same volume used for the 2024 and 2026 craft and for the FX HO and FX HO with audio.
A manual that spans three consecutive years is a sign of a stable platform, and it also means you can see at a glance where something was revised between builds. That is genuinely useful when a part number changes mid-generation.
The service content includes engine overhaul, jet pump and driveline work, fuel and cooling systems, hull and deck hardware, and the full electrical schematics with the audio system in place. Torque values, clearances and wear limits sit with the procedures. Troubleshooting is arranged around symptoms, so you start from what the craft is doing and work backwards. Verify FX1900A-BA on your plate first.
