2000 Yamaha WaveRunner XL800 PWC Service Manual (P/N LIT-18616-02-14)

This Yamaha service manual covers the 1999–2000 WaveRunner XL800 personal watercraft with the F0P hull and 67A engine. It is the first edition, December 1999, publication LIT-18616-02-14; the cover also carries manual code F0P-28197-ZA-11.

Text search and wiring detail: Searchable PDF text and bookmarks provide access to the nine chapters, individual sections, and final wiring diagram. Small connector labels and wire-color codes are readable when enlarged. The additional “Return to Index” bookmark requires a separate file not included here.

• Power unit repair: Engine removal and installation, cylinder and piston inspection, crankcase disassembly, crankshaft checks, and YPVS valve service.

• Fuel and oil injection: Dual Mikuni BN44 carburetor synchronization, accelerator pump and fuel pump service, oil pump cable adjustment, and air bleeding.

• Jet pump service: Impeller and drive shaft removal, bearing replacement, oil seal installation, bearing housing alignment, and reverse gate assembly.

• Steering and trim: QSTS grip disassembly, steering master inspection, and steering, throttle, choke, shift, and QSTS cable adjustments.

• Electrical diagnosis: Ignition, starting, charging, YPVS, and indication-system wiring diagrams, peak voltage tests, starter motor inspection, and multifunction meter checks.

• Hull repair: Fiberglass scratch, crack and puncture repairs, insert-nut work, and graphic removal and installation, with references to Yamaha’s separate FRP repair manual.

Yamaha wrote this manual primarily for its dealers and trained mechanics, assuming a working knowledge of mechanical and electrical service procedures.

Power Unit Inspection and Reassembly

The engine sections cover the exhaust chamber and manifold, reed valves, cylinder head, pistons, flywheel magneto, starter clutch, crankcase, and crankshaft. Inspection criteria address water-jacket deposits, cylinder wear, piston rings, bearings, and seals.

The cylinder-and-piston matching table links cylinder size markings to piston color codes, helping identify the correct piston before selecting rebuild parts. Engine removal and installation instructions also cover mount shims and coupling clearances.

Flywheel removal notes explain how incorrect puller positioning can damage the engine or tools.

Carburetors and Oil Injection

Exploded diagrams and job instruction charts cover the fuel cock, intake silencer, carburetor unit, and fuel pump. Internal carburetor checks address diaphragms, the regulator body, needle valves, and the accelerator pump.

Oil injection coverage includes check-valve inspection, cable adjustment, and pump air bleeding. Carburetor service notes warn that steel-wire cleaning can enlarge jets and impair performance.

Jet Pump, QSTS, and Steering

Jet pump bearing replacement procedures specify pullers, press attachments, and seal installation details. The manual also covers stainless-steel impeller inspection, drive shaft checks, and bearing housing shims.

Reverse gate illustrations identify lever and spring positions. QSTS grip and steering master sections include disassembly charts; cable and hose routing diagrams support control-cable installation and adjustment.

Electrical Tests and Fault Tracing

CDI peak voltage parameters, stator charge and pickup coil resistance values, and test connection diagrams support ignition diagnosis. Loaded and unloaded test conditions help distinguish a component fault from an unsuitable test setup.

The electrical analysis section identifies the peak voltage adapter YU-39991 / 90890-03169 and eight-pin test harness YW-06779 / 90890-06779. Charging tests cover the lighting coil and rectifier/regulator.

YPVS servomotor coverage consists of removal, testing, replacement, and cable adjustment; the sealed motor is not intended for internal overhaul. Multifunction meter checks cover display operation, fuel and oil indications, overheat warnings, and speed-sensor signals.

The two-page Trouble Analysis Chart links symptoms such as starting problems, overheating, bilge water buildup, and poor charging to relevant components and chapters.

Fuel vapor and sparks make ignition testing hazardous; the manual’s safety precautions and factory tolerances apply throughout engine service.

Fiberglass Hull and Deck Repair

Hull repair drawings accompany scratch, crack, puncture, and insert-nut procedures. For cracks, punctures, and insert-nut work, Yamaha directs the reader to the separate Water Vehicle FRP Repair Manual, which is not included in this PDF.

Maintenance Charts and Service Specifications

The maintenance interval chart covers periodic inspections and lubrication. Reference tables provide fluid capacities, compression specifications, clearances, wear limits, spark plug settings, and electrical test values. Component-specific torque tables include cylinder-head tightening stages and flywheel magneto fasteners.

English PDF and Included Pages

One printable English PDF. The 238-page PDF includes 215 numbered service pages, 14 chapter contents pages, seven opening pages including the cover, one back-cover page, and the final color XL800 wiring diagram.
