On a 2026 252SD the code to look for is BXT1900B-CAP, and Yamaha covers the boat in service manual LIT-18616-04-41.
That number has been the reference for this platform since the 2024 models, and it carries the 252S, 252SE, 252XE, AR250 and SX250 in the same volume. The engines, pumps and harnesses are common enough that one set of procedures serves all of them, with model notes where needed.
- Engine service, from scheduled checks to complete teardown
- Jet propulsion unit procedures and clearances
- Published torque values and wear limits
- Factory wiring diagrams for every circuit
- Symptom-based troubleshooting and maintenance intervals
Quote LIT-18616-04-41 when you want the manual and BXT1900B-CAP when you want a part, and the counter can check both against the same records the dealer uses.
