2025 Yamaha 252 FSH SPORT Service and Repair Manual
Yamaha lists the 2025 252 FSH SPORT as KXT1900A-BAP and covers it in service manual LIT-18616-04-45, the same number issued for the 2024 and 2026 boats.
Three model years under one part number tells you something practical: the platform did not change materially across them, so torque values, wiring and diagnostic procedures carry over. It also means the manual is written at a level of detail that expects measurement, not estimation.
Expect factory removal and installation order for the engine and jet pump, published clearances and wear limits, complete electrical schematics for ignition, charging, gauges and accessories, symptom-led troubleshooting, and scheduled maintenance intervals. Hull, deck and control-system adjustments are covered too, which is where much of the routine work on a boat this size actually happens.
Confirm KXT1900A-BAP on the plate; LIT-18616-04-45 is the number to quote for the manual itself.
