Model code BXT1900C-AAP belongs to the 2024 252SE. The factory service manual carrying its procedures is Yamaha LIT-18616-04-41.
It is a shared book. The 252S, 252SD, 252XE, AR250 and SX250 appear in it too, and its coverage extends through the 2025 and 2026 model years. Yamaha takes that approach across the 25-foot range because the mechanical core is common; deck layout and equipment are what separate the trims.
Level of detail
This is not owner-manual material. Fasteners come with torque figures, assemblies come with clearances, and components come with the service limits that decide whether they are reusable. Wiring is shown in full factory diagrams rather than block sketches, and the diagnostic chapters work from a reported symptom through ordered checks.
Confirm BXT1900C-AAP before ordering anything.
