2020 Yamaha SX210 Service and Repair Manual

LIT-18616-03-73 is the part number behind this one, and it is a broad book. Yamaha used it for the 21-foot sport boat range from 2017 to 2022, taking in the 212 family in nearly all its forms, from the 212S and 212X to the various Limited, LTD and California variants, along with the AR210.

For a 2020 SX210 the code on the plate should be LBT1050B-V. That is worth checking first, because so many closely related hulls share this volume.

The material itself is standard factory service fare done properly: torque values, assembly clearances, engine and jet pump overhaul steps, fuel and cooling system work, complete wiring diagrams, and troubleshooting charts organised by symptom. Because the book spans several years, it also lets you see where your boat sits relative to the ones built either side of it.
