Model code KPT1800A-BAP, service manual LIT-18616-04-44. Those are the two numbers that define what fits a 2025 255 FSH SPORT E.
Scope of the book
Yamaha issued it for the 2024 through 2026 model years and included the 255 FSH SPORT H in the same coverage. A single volume across three years means the specifications you look up were confirmed against the whole run, not only the boat in front of you.
Everything is at dealer level: factory removal and installation sequences for engine and jet pump, published torque and clearance data, service limits for judging wear, full wiring diagrams for ignition, charging, gauges and accessories, and symptom-based diagnostic procedures. Maintenance intervals are given by operating hours and by season.
Worth confirming KPT1800A-BAP on the plate before any parts order, since the E and H variants overlap in this manual.
