The 2024 AR220 carries hull code HLT1050A-AAP, and the service manual Yamaha wrote for it is LIT-18616-04-29.
That same book runs from 2023 to 2026 and takes in the 222S, 222SD, 222SE, 222XD, 222XE and SX220. Yamaha groups these boats because they are built on common architecture, so a job described once serves the whole family. It also means the application list is the first page worth reading, since the specifications given for a related hull are not always identical to yours.
Expect complete overhaul procedures with the specified order of operations, torque and clearance tables, wiring diagrams, maintenance schedules, and troubleshooting laid out from observed symptom to likely cause.
A technician who has the part number and the code in hand can be confident the figures on the page belong to the boat on the trailer.
