LIT-18616-04-29 is the Yamaha service manual covering the 2024 SX220, a boat built under hull code HLT1050B-AAP.
Four seasons share this volume, 2023 to 2026, and so do the 222S, 222SD, 222SE, 222XD, 222XE and AR220. The platform is common across the group, which is why Yamaha wrote once and applied it widely.
Practically, the manual gives you the order of operations for each job, the torque figures and service limits that decide whether a component goes back in, wiring diagrams for chasing electrical problems to their source, the maintenance schedule, and troubleshooting arranged by symptom.
One caution worth repeating: read the application list and confirm HLT1050B-AAP. Sister hulls in this book are not identical, and the code is how the manual tells them apart.
