Yamaha Waverunner XL760/XL1200 + XL700 Service Manual Set, 1998–2004 (P/N LIT-18616-01-88)

The XL700 supplement adds model-specific service information and directs unchanged procedures to the XL760 sections of a companion service manual.

Companion-manual reference: The supplement specifically names GU2-28197-Z7-C1. That edition is not included; the base manual supplied here is the U.S. edition listed above.

PDF Search, Chapter Access and Wiring Detail

Search and navigation: The main manual has no PDF text search, but its embedded bookmarks open the service chapters. The supplement has searchable text; its bookmarks mainly open contents pages. Small wiring labels in both PDFs require zooming.

One ZIP contains two printable PDFs totaling 315 pages. The totals include seven front-matter pages in the main manual, nine front-matter pages and one back cover in the supplement. The main manual is in English; the supplement includes English, French, German, and Spanish.

Engine, Jet Pump and Electrical Service

The following selected service topics outline the repair coverage rather than reproduce the full contents. Other subjects include fuel-tank pipe-joint service and ventilation-system inspection.

• Engine repair: Step-by-step procedures cover engine removal, cylinder and piston inspection, crankcase and crankshaft service, and coupling alignment.

• Carburetor service: Diaphragm and needle-valve inspection, throttle synchronization, model-specific choke adjustments, high- and low-speed screw settings, and fuel-pump disassembly.

• Oil injection: Pump and check-valve inspection, system air bleeding, and the XL1200 oil-pump cable adjustment.

• Jet pump service: Pump removal, impeller and drive-shaft service, bearing installation, and intake-duct bushing and oil-seal replacement.

• Electrical diagnosis: CDI ignition, starting and charging tests, sensor checks, model-specific wiring diagrams, and multifunction-meter checks.

• Steering and hull: Control-cable replacement and adjustment, reverse-gate service, and fiberglass scratch, puncture, and insert-nut repairs.

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

Fuel, Lubrication and XL700 Differences

These water-cooled, reed-valve two-stroke engines use oil injection. The XL700 supplement addresses the 701cc 67E twin with its own carburetor settings, engine-assembly details, electrical tests, and oil-level warning-lamp checks.

The carburetor notes explain how steel-wire cleaning can enlarge jets and affect performance. Exhaust service covers the chamber, muffler, water lock, and cooling-water hoses.

Shaft Installation and Hull Repair

Jet-pump and intermediate-housing procedures distinguish model-specific bearing positions and shaft installation depths for the two main models. Exploded views of the Crankcase, Impeller and Drive Shaft, and Cooling and Bilge System accompany parts callouts and removal/installation charts.

Special-tool references identify the YB-06117 flywheel puller and YB-06049 drive-shaft holder. Flywheel-removal cautions explain how uneven puller installation can damage the engine or tools.

Hull-repair material covers light and deep scratches, punctures, and insert-nut repairs. Further fiberglass repair details are referenced to the separate Water Vehicle FRP Repair Manual, which is not included.

Fault Analysis and Electrical Tests

The Trouble Analysis charts connect symptoms to components and repair chapters, helping mechanics choose the relevant inspection before disassembly. They address no-starts, rough idling, overheating, increased bilge water, and poor performance.

The Ignition System and Indication System wiring diagrams include wire-color keys; the main electrical diagrams also provide connector views. Multifunction-meter tests cover display operation, warning indications, and the security function.

The XL700 supplement adds peak-voltage tests for the CDI unit, charge and pulser coils, lighting coil, and rectifier/regulator. It distinguishes connected-system and disconnected-coil measurements and specifies peak-voltage adapter 90890-03169.

The base manual also explains how test-meter resistance affects low-resistance measurements. Reference tables provide component-specific tightening torques, fluid capacities, crankshaft clearances, and electrical test specifications.

Have a certified marine technician oversee or verify critical powertrain maintenance, particularly work involving fuel vapors and ignition sparks.

Piston-Clearance Specification Preview

For the XL760 and XL1200, the piston inspection specifications list a standard piston-to-cylinder clearance of 0.100–0.105 mm and a wear limit of 0.155 mm.

The XL700 supplement specifies a standard clearance of 0.080–0.085 mm and a wear limit of 0.135 mm, keeping its piston-fit data separate from the base models.
