2024 Yamaha 255XD Service and Repair Manual
Yamaha lists the 2024 255XD as BPT1800G-AAP and documents it in service manual LIT-18616-04-40.
The 255XE is covered by the same part number, and the manual holds good for the 2025 and 2026 model years too. Two model names, three years, one consistent set of specifications.
The book works through periodic maintenance, engine service, the jet propulsion unit, hull and deck hardware, steering and control systems, and the electrical installation. Fasteners carry published torque values, assemblies carry clearances, and components carry the service limits that tell you whether to reuse or replace. The wiring diagrams are complete factory drawings, and the diagnostic chapters start from the symptom and narrow down through ordered checks.
Keep BPT1800G-AAP with you at the parts counter. On a platform where two models share a manual, the model code is what resolves a part number.
