Model code BPT1800E-AAP identifies the 2024 255XE. The service manual Yamaha published for it is LIT-18616-04-40.
That same book covers the 255XD and remains the current reference for 2025 and 2026 boats. The factory consolidated the two models because their engines, pumps, steering and electrical systems are shared; deck and equipment differences are handled with notes.
Contents are organised by system. Periodic maintenance comes first, then engine service, jet propulsion, hull and deck, controls, and electrical. Torque figures, assembly clearances and service limits are published values, not estimates. Wiring is shown in complete diagrams, which is what you need when a fault is intermittent rather than obvious.
Confirm BPT1800E-AAP on the plate before ordering. Between the XD and XE, the code is more reliable than the badge.
