The 2024 252SD wears model code BXT1900B-AAP, and the manual written for it is Yamaha LIT-18616-04-41.
Anyone who has worked on this platform knows the pattern by now. That part number is the common reference for the 252S, 252SE, 252XE, AR250 and SX250 as well, over the 2024, 2025 and 2026 model years. The shared machinery justifies it, and the text distinguishes models where the specifications part company.
Coverage runs from the periodic maintenance chart through engine service, jet propulsion overhaul, hull and deck hardware, steering and control linkage, and the electrical system. Torque figures, assembly clearances and service limits are given as published. Wiring diagrams are the complete factory drawings. Troubleshooting sections are organised the way faults present themselves on the water.
