1995–1996 Yamaha WaveVenture WVT700 PWC Service Manual (P/N GJ3-28197-Z5-11)

This factory service manual covers the 1995–1996 Yamaha WaveVenture WVT700, including its 701 cm³ two-stroke engine and jet pump propulsion system. It carries P/N GJ3-28197-Z5-11; the cover also identifies LIT-18616-01-27.

One 164-page PDF in English, organized into nine chapters.

• Engine & Power Unit: Engine removal, cylinder and piston service, crankcase disassembly and crankshaft inspection, with reed valve and exhaust component repair.

• Fuel & Induction: Twin-carburetor disassembly, throttle and choke synchronization, fuel delivery checks, oil injection pump inspection and air bleeding.

• Drive & Propulsion: Jet pump removal, impeller and drive shaft service, intermediate housing bearings and seals, and coupling alignment.

• Electrical Systems: System-specific wiring diagrams, CDI ignition tests, starter-motor repair, charging checks and fuel/oil level indicator diagnosis.

• Controls & Hull: Steering and shift cable adjustment, handle column service, reverse gate disassembly and fiberglass hull repair.

• Service Specifications: Maintenance intervals, torque tables, spark plug gap specifications, fluid capacities, wear limits, electrical test values and adjustment data.

Yamaha prepared this manual for its dealers and trained mechanics, with basic mechanical and electrical knowledge assumed.

Engine Repair and Coupling Alignment

The power unit section provides cylinder head warpage limits, piston-to-cylinder clearance specifications, ring clearances and crankshaft inspection data. Removal and installation charts accompany exploded views such as Cylinder Head, Cylinder and Piston.

Coupling clearance and engine mounting shim information help restore engine-to-intermediate-shaft alignment after removal. Tool references include flywheel puller YB-06117 / 90890-06521 and coupler wrench YW-38741 / 90890-06425.

The flywheel procedure warns that uneven puller setup can damage the engine or tools.

Carburetors and Oil Injection

The manual distinguishes the front and rear carburetors, including their different main jets and high-speed screw settings. Diaphragm, float-arm and needle-valve inspections support carburetor repair; throttle and choke synchronization are treated separately.

Fuel tank check-valve inspection and oil injection pump bleeding are also documented. The carburetor section warns that cleaning jets with steel wire can enlarge their openings and affect engine performance.

Jet Pump, Cooling and Hull Work

Impeller service identifies the left-hand thread and drive shaft holder YB-06049 / 90890-06518. Bearing and oil seal procedures cover both the pump and intermediate housing, while the Cooling and Bilge System exploded view shows hose, strainer and valve-body connections.

Hull repair extends to light and deep scratches, punctures, insert nuts and graphics. The text refers to the separate Water Vehicle FRP Repair Manual for further fiberglass repair information; that publication is not included in this PDF.

Electrical Diagnosis and Troubleshooting

Dedicated Ignition System, Starting System, Charging System and Indication System wiring diagrams sit alongside component tests. These cover the CDI unit, ignition and stator coils, engine stop switch, starter relay, rectifier-regulator, thermo switch and multifunction meter.

Starter-motor repair includes armature, commutator and brush-holder inspection. The Trouble Analysis Chart links symptoms such as no-start, poor charging, overheating and increased bilge water to components and reference chapters, helping narrow the checks before parts are replaced.

Observe Yamaha's fuel-vapor and spark-test precautions when working on the ignition system.

File Format and Readability

The total comprises 154 pages of manual content and front matter, one combined front/back cover sheet and nine blank pages. All are included in the stated 164 pages; there is no separate supplement.

Text search works on the cover only. The service pages have no embedded searchable text. The 164 embedded bookmarks are unnamed page links, so navigation relies on page numbers and printed chapter indexes.

Small wire-color codes and component labels in the electrical diagrams are readable when enlarged.
