Yamaha WaveVenture 700, 760 & 1100 PWC 1995–1998 Service Manual Set

The separate WVT760 manual complements the combined WVT700/WVT1100 manual with its own mechanical and electrical specifications. Keeping these model-specific sections distinct helps match carburetor settings, ignition tests, and assembly details to the watercraft being serviced.

For detailed fiberglass work, the hull chapters also refer to the separate Water Vehicle FRP Repair Manual, which is not included.

PDF Bookmarks and Wiring Detail

Navigation and diagram labels: Manual pages do not support PDF text search. Embedded bookmarks cover chapters and many component sections in both publications. Small wire-color codes and connector labels in the wiring diagrams are best read with zoom.

One printable, English-language PDF contains 339 pages, including both publications and one additional page between them.

Engine, Jet Pump and Electrical Service

The following selected coverage highlights show the main workshop areas. Other topics include drain-plug inspection and graphic removal and application.

• Power unit repair: Step-by-step engine removal, cylinder and piston service, crankcase disassembly, crankshaft inspection, and reassembly.

• Fuel and oil injection: Carburetor disassembly, throttle and choke synchronization, fuel-pump inspection, oil-pump service, and oil-injection air bleeding.

• Jet pump service: Pump removal, nozzle deflector and reverse-gate disassembly, impeller and drive-shaft service, and cooling and bilge-system inspection.

• Electrical diagnosis: Ignition, starting, charging, and indication-system wiring diagrams, component tests, starter-motor inspection, and trouble-analysis charts.

• Periodic maintenance: Maintenance interval charts, steering and shift-cable adjustments, spark-plug inspection, battery checks, and bilge-strainer service.

• Hull and hood: Engine-hood and deck disassembly, seat and storage-box service, gelcoat repairs, and punctured fiberglass-hull repair procedures.

These manuals present Yamaha’s recommended service procedures for Yamaha dealers and their mechanics.

Power Unit Inspection and Assembly

The power unit sections extend to the reed-valve assemblies, exhaust ring, exhaust chamber, muffler, flywheel magneto, and intermediate shaft and housing. Cylinder-head and crankcase torque data accompany inspection specifications for cylinders, pistons, rings, crankshafts, and bearings.

Assembly details: Engine-removal notes preserve mounting-shim locations for coupling alignment, while top-end assembly diagrams flag piston-pin clip orientation. The flywheel procedures identify puller YB-06117/90890-06521 and warn that uneven puller loading can damage the engine or tools.

Carburetor Synchronization and Oil Supply

Separate throttle and choke synchronization procedures address the dual-carburetor WVT700 and WVT760 configurations and the triple-carburetor WVT1100. Diaphragm, float-arm, needle-valve, and jet inspections accompany the model-specific adjustment settings.

The WVT1100 fuel pump has its own disassembly section. Oil-system coverage includes tank and filter checks, delivery-hose inspection, and air bleeding after system disassembly or loss of the oil supply.

Jet Pump, Bearings and Bilge Routing

The Nozzle, Duct and Intake and Impeller and Drive Shaft exploded views show bushing, bearing, and oil-seal placement. Intermediate-housing service includes coupling inspection and bearing removal and installation, with the specified shaft holders and bearing attachments.

Cooling and bilge layouts are illustrated separately for WVT700 and WVT1100. The WVT760 publication provides its own cooling and bilge-system section.

Electrical Tests and Fault Tracing

The Ignition System, Starting System, Charging System, and Indication System wiring diagrams accompany switch-continuity checks and coil tests. Multifunction-meter checks address the overheat, fuel, and oil-warning displays.

Low-resistance measurement guidance accounts for the tester’s internal resistance. Trouble Analysis Charts connect symptoms such as failure to start, stalling, overheating, and increased bilge water with relevant components and chapter references.

Hull Repairs and Workshop Safety

Hull procedures cover light and deep scratches, punctured fiberglass, and insert-nut repairs. Hood, exhaust-hose, water-lock, gunwale, and mat sections provide the related removal and inspection information.

Always follow standard workshop safety protocols and verify your technical capability before attempting complex procedures. Fuel-vapor and ventilation precautions are particularly relevant to work inside the engine compartment.

Reed, Piston and Jet Pump Specification Examples

Reed-valve inspection: The service procedures specify a valve stopper height of 9.0 ± 0.2 mm for WVT700, WVT760, and WVT1100.

Piston inspection: The WVT760 specifications give a standard piston-to-cylinder clearance of 0.100–0.105 mm and a wear limit of 0.155 mm.

Jet pump inspection: The impeller-to-duct clearance service limit is 0.6 mm across the covered models, alongside the related impeller, shaft, and bearing inspection procedures.
