Yamaha WaveRaider RA700 / RA760 / RA1100 Service Manual Set, 1994–1997 (P/N LIT-18616-RA-00)

Use the model-specific supplements alongside the base manual for procedures they do not repeat. They provide revised service information for the RA700BU and RA760.

Both supplements name LIT-18616-01-26 as their original companion manual; the base publication included here carries P/N LIT-18616-RA-00.

PDF Bookmarks, Text Search and Diagram Detail

Navigation and small labels: The technical manual pages are not text-searchable. Embedded bookmarks cover the chapters and both supplements, although some destinations are slightly offset. Small wire-color codes and connector labels in the wiring diagrams require zooming for comfortable reading.

One printable, English-language 276-page PDF contains all three publications. The total also includes one compilation cover and five inserted storage pages.

Engine, Fuel-System and Jet-Pump Service

The following is a selection of covered work, rather than a full contents list. Other topics include water-separator inspection and graphic removal and installation.

• Engine repair: Step-by-step engine removal, cylinder-head and piston work, crankcase disassembly, crankshaft inspection, reed-valve service, and flywheel magneto removal.

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

• Jet-pump service: Pump removal, impeller clearance inspection, drive-shaft disassembly, bearing and seal replacement, and cooling- and bilge-system inspection.

• Electrical diagnosis: Ignition, starting, charging and indication wiring diagrams, component resistance tests, starter-motor disassembly, and fuel- and oil-level sensor checks.

• Steering and hull: Steering, throttle, choke and trim-cable adjustment, handle-column inspection, hood removal, exhaust-system service, and fiberglass hull repairs.

• Trouble analysis: Symptom-based charts connect starting problems, rough idle, overheating, poor performance, bilge-water accumulation and charging faults with relevant inspection areas.

Written primarily for Yamaha dealers and their trained mechanics, these publications assume a basic understanding of mechanical and electrical service concepts.

Bench Work, Alignment and Rotating Assemblies

Exploded diagrams pair numbered components with removal and installation charts and detailed service points. This layout supports bench work by keeping assembly relationships, inspection criteria and model-specific tightening information close to the work being described.

Crankshaft inspection covers runout, connecting-rod clearance and bearing condition. Intermediate-shaft and housing sections explain bearing removal, coupling inspection and oil-seal installation, while the jet-pump chapter separates nozzle, duct and intake work from impeller and drive-shaft service.

The RA760 supplement includes its own coupling-alignment and shim information. Flywheel procedures identify tools such as puller YB-06117/90890-06521 and warn that incorrect puller engagement can damage the engine or tools.

Carburetor Differences and Storage Maintenance

The RA700B supplement addresses its single-carburetor arrangement. RA760 procedures cover dual carburetors, while the RA1100 has a three-carburetor assembly with its own synchronization instructions.

Oil-pump bleeding is specified after system disassembly or after the oil supply has run empty. The storage section covers cooling-system flushing, lubrication, fuel preparation and battery care.

The flushing cautions explain how incorrect water-supply timing can allow water to flow back through the muffler into the crankcase and cause severe engine damage.

Circuit Tests and Fault Isolation

Electrical component views identify connectors and lead colors alongside the circuit diagrams. Tests cover ignition coils, charge and pulser coils, switches, the starter relay, rectifier-regulator and multifunction meter.

The electrical analysis section also explains how tester internal resistance affects low-resistance measurements. Together with the trouble-analysis charts, these references help mechanics connect a reported symptom with the appropriate circuit or component check.

Controls, Exhaust and Hull Repairs

Hull and hood coverage includes trim-control grip service, cable replacement, exhaust-hose and water-lock inspection, and ventilation-system removal.

Hull repair instructions address scratches, punctures and insert-nut repairs, with references to the separate Water Vehicle FRP Repair Manual for further detail.

Follow the manual’s precautions for fuel vapors, engine testing and rotating components, and use the specified service tools.

Carburetor, Intake-Screen and Piston Data Examples

RA1100 carburetor adjustment data includes a low-speed screw setting of 1-1/8 ± 1/4 turns out. The base manual’s jet-pump inspection section specifies 11 N·m (8.0 lb-ft) for the intake-screen bolts.

The RA760 supplement gives a standard piston-to-cylinder clearance of 0.100–0.105 mm in its piston inspection procedure. Model-specific bore, piston and ring inspection data accompany these service specifications.
