2025 Yamaha 275SD Service and Repair Manual
The 2025 275SD is a different service subject from the earlier boats of that name. Its code is FPT1800D-BA, and the manual written for it is Yamaha LIT-18616-04-28.
That volume also covers the 275SDX, and its model-year coverage is 2023, 2025 and 2026. If you have been working from LIT-18616-04-28 on an older 275, note that this is separate literature and the specifications are not interchangeable.
Chapters work through periodic maintenance, engine service, the jet propulsion units, hull and deck hardware, steering and controls, and electrical. Torque figures, clearances and service limits are given as published. The wiring diagrams are complete factory drawings, and the troubleshooting sections proceed from a reported symptom.
FPT1800D-BA is the code to verify before you order parts.
