For 2024 the 222XD is built as HXT1900A-AAP, and the manual that matches it is LIT-18616-04-42, covering the 222S, 222SD, 222SE and 222XE through 2026.
Note the shift away from the earlier 222 literature. The 1900-series hulls have their own book, and confirming the code on the plate is how you avoid working from the wrong specifications.
Once you have the right volume, the work becomes predictable. Access sequences are given, fasteners have torque values, components have wear limits, systems have inspection routines, and circuits have diagrams. Engine, jet pump, driveline, fuel, cooling, exhaust, steering, controls, plumbing, instrumentation and deck hardware are all in scope.
Troubleshooting begins with the symptom, which is how a fault actually arrives, and the maintenance schedule is set out for both hours run and time elapsed.
