Yamaha LIT-18616-04-28 is the service manual for the 2023 275SDX, model code FPT1800D-YB.
The 275SD shares that part number, and the manual's coverage lists the 2023, 2025 and 2026 model years. The gap in that list is worth noticing when you are matching literature to a boat, and it is another reason to work from the model code rather than the year alone.
- Engine service through to complete disassembly
- Jet propulsion unit procedures and clearances
- Published torque values and service limits
- Complete wiring diagrams for every circuit
- Symptom-based troubleshooting and maintenance schedule
This is the reference a dealer technician uses on the boat, written to be followed in sequence with a torque wrench and a meter to hand. Confirm FPT1800D-YB against the certification plate before ordering.
