KXT1800A-X is the model code stamped for the 2022 252 FSH SPORT. The service manual Yamaha assigned to it is LIT-18616-04-23.
One book, three model years, two boats. Yamaha published LIT-18616-04-23 for the 2021 through 2023 252 FSH SPORT and for the 255 FSH SPORT E of the same period, flagging the places where the two diverge instead of splitting the text.
What you get is the dealer-level reference: complete removal and installation procedures for the engine and jet pump, published torque values and service limits, hull and deck hardware work, steering and control adjustment, and the factory wiring diagrams. Diagnosis is organised around symptoms, so a hard-starting engine or an erratic gauge sends you to a sequence of checks rather than a guess.
Verify the code KXT1800A-X against the certification plate before ordering, since neighbouring model years are not always interchangeable.
