A new part number arrived with the 2024 boats. LIT-18616-04-45 replaced the earlier literature, and the 2024 252 FSH SPORT under it is coded KXT1900A-AAP.
Yamaha carried this manual forward through 2025 and 2026, so a procedure you look up today still applies to the newer hulls. Unlike much of the sport-boat range, the manual does not fold in other model names; it stays with this boat across those three years.
Contents
Periodic maintenance tables, engine service from routine checks through teardown, jet propulsion unit work, hull and deck hardware, steering and control systems, and the electrical section with full factory diagrams. Torque figures and service limits sit with the procedures they belong to. The troubleshooting chapters are built around what goes wrong in service rather than around theory.
Check KXT1900A-AAP before you order.
