2024 Yamaha GP1900 HO w/ audio Service and Repair Manual

Yamaha issued one service book for the GP1900 HO platform, and part number LIT-18616-04-37 is the one that covers this 2024 machine, built under model code GP1900A-AB.

The same volume carries the 2024, 2025 and 2026 model years, and it also documents the GP1900 HO without the audio package, so a shop working several hulls of this generation only needs the single reference.

What the manual covers

• Engine and jet pump removal, inspection limits and reassembly
• Torque figures and tightening sequences as Yamaha specifies them
• Fuel, cooling, electrical and steering system diagnosis
• Wiring diagrams and connector locations
• Periodic maintenance intervals and adjustment procedures

Before ordering, check the model code on the hull identification plate against GP1900A-AB. Codes change between years even where the bodywork does not, and matching the code is how you confirm the procedures and specifications apply to your craft.
