By 1991 the Wave Runner was coded WR500P, still documented in Yamaha's LIT-18616-00-52. That manual covers the 1988, 1990 and 1991 model years, and the Wave Jammer and Wave Runner LX appear in it too.
A shared book across those years reflects how little changed mechanically between them, and it means a single reference answers most questions about a WR500P.
What it provides
- Yamaha's own torque specifications and service limits
- Procedures in the factory's order of work
- The wiring diagram for circuit tracing
- Diagnostic sequences rather than lists of guesses
Note both WR500P and LIT-18616-00-52 in your records. Between them they identify exactly what you have and what it was serviced against.
Coverage also extends to the sibling craft, so components shared across the three model years are described once and apply broadly. That helps whenever a repair reaches a shared assembly.
