BPT1800G-BAP on the plate means a 2025 255XD, and the factory manual for it is Yamaha LIT-18616-04-40.
What the part number covers
Yamaha wrote LIT-18616-04-40 for the 255XD and 255XE across the 2024, 2025 and 2026 model years. Because it spans all three, a procedure looked up for one year has already been reconciled with the others.
Expect factory disassembly and reassembly order for the engine and jet pump, published torque and clearance data, service limits, full wiring diagrams covering ignition, charging, gauges and accessory circuits, symptom-led troubleshooting, and the maintenance schedule with fluid specifications.
It is written for a technician, which mainly means it assumes you will take a measurement where it asks for one. Confirm BPT1800G-BAP against the certification plate before ordering parts.
