Part number LIT-18616-01-76 is the factory service manual a technician reaches for on a 1999 GP760, model code GP760X. One book, four model years, 1997 through 2000, and the WaveRunner GP 1200 shares it.
Everything is organised the way the craft comes apart: hull and hood hardware, fuel delivery, power unit, jet pump unit, drive system, electrical. Yamaha gives standard and limit dimensions for the wearing parts, torque for each fastener group, and the sequence in which bolts are pulled up.
The troubleshooting section is worth reading before spending money. It separates fuel, spark and compression symptoms so you can narrow a running complaint without guessing at parts. Verify GP760X on your hull plate, since the two-stroke GP models changed code letter each season.
