Coverage for the final GP760 year, model code GP760Y, comes in LIT-18616-01-76. Yamaha published it once for the 1997 to 2000 run and included the WaveRunner GP 1200 in the same volume, so the book handles more than the one craft on its cover.
It is the dealer document: exploded views, service limits for pistons, bearings and the pump, carburetor settings, ignition timing and electrical resistance values, plus the wiring diagrams. Assembly notes call out where sealant or new gaskets are required.
Owners doing their own winter work tend to use the periodic maintenance chapter and the pump section most. Anyone rebuilding an engine will live in the specification tables, where standard and limit dimensions sit side by side so a measured part can be judged instead of guessed at. Either way, confirm GP760Y on the hull plate before you begin.
