A 2025 255 FSH SPORT H reads KPT1800B-BAP on the certification plate, and Yamaha assigns it service manual LIT-18616-04-44.
One volume covers 2024, 2025 and 2026, and it takes in the 255 FSH SPORT E as well. That consolidation is the factory's, so specifications carry the same authority they would in a single-model book.
Using it on a fishing boat
Gear that lives in salt water needs the maintenance schedule more than most, and the manual gives intervals by operating hours and by season, along with the flushing, layup and recommissioning procedures. Beyond that you get factory removal and installation order for the engine and jet pump, published torque and clearance figures, service limits, complete wiring diagrams and symptom-based diagnosis.
Confirm KPT1800B-BAP before ordering.
