Yamaha FZR/FZS WaveRunner Service Manual 2009–2013 (P/N LIT-18616-03-18)

Yamaha service manual P/N LIT-18616-03-18 covers FZR GX1800 (F2R) and FZS GX1800A (F2C) WaveRunners. This is the first edition, January 2009, ©2009 Yamaha Motor Corporation, USA, with document number F2C-28197-1M-11.

Searchable PDF and Color Wiring Diagram

Text search and diagram detail: The service chapters have searchable text and embedded bookmarks for chapters and individual procedures. Small connector numbers and wire-color codes in the wide color wiring diagram require zooming for comfortable reading.

The download is one printable, English-language, 401-page PDF. That total includes the front and back matter, five memo pages, one blank page, and the color wiring diagram.

Engine, Jet-Pump and Control-System Service

These selected service topics show part of the manual’s coverage. Other sections include electric bilge-pump testing and Yamaha Security System transmitter registration.

• Engine repair: Step-by-step procedures for engine removal and installation, camshaft and timing-chain work, cylinder-head service, and crankcase, piston and connecting-rod repair.

• Jet-pump service: Pump removal and installation, reverse gate and nozzle work, impeller duct and housing inspection, drive-shaft service, and bearing and seal replacement.

• Fuel system: Tank, pump module, sender, rollover and check valves, injectors, quick connectors and fuel rail, with fuel-pressure testing.

• Electrical diagnosis: Ignition and charging tests, starter-motor disassembly and inspection, sensor checks, wiring diagrams, and connector identification.

• Yamaha Diagnostic System: ECM diagnostic codes, sensor monitoring, stationary and active tests, data logging, and recorded fault-data analysis.

• Hull and controls: Telescopic steering master, QSTS grip and converter, remote control cables, shift system, seats, handgrips, exhaust system, and deck/hull disassembly.

• Periodic service: Maintenance schedules, oil and filter changes, compression testing, valve-clearance checks, cable adjustments, lubrication points, and bilge-strainer maintenance.

Yamaha prepared this manual primarily for its dealers and trained mechanics, assuming a basic understanding of mechanical and electrical service procedures.

Engine Internals and Lubrication

Valve service extends to guide replacement, seat refacing and valve-pad selection. Crankshaft and connecting-rod bearing procedures include Plastigauge measurements and color-coded bearing selection; engine installation also covers coupling alignment and shim adjustment.

Generator and flywheel service includes starter-clutch checks. Supercharger drive-gear work and trochoid oil-pump inspection and priming are also covered. Referenced tools include camshaft wrench 90890-06724 and coupler wrench 90890-06729.

The wet-sump lubrication and TCI ignition systems are documented alongside the engine repair procedures. The Lubrication system and Cooling system views trace their respective circuits, while the specifications distinguish total oil capacity from oil-change quantities with and without filter replacement.

Assembly limits: Yamaha prohibits internal disassembly of the supercharger, throttle body, air cooler, oil cooler, oil pump assembly and breather assembly. Their sections cover the specified inspections, tests and replacement work. Air- and oil-cooler holding-pressure checks are included, using leakage tester 90890-06840 and air-cooler attachment 90890-06731 where specified.

Fuel Delivery and Jet-Pump Repair

Fuel-pressure measurement is supported by adapter YW-06842 / 90890-06842 and gauge YB-06766 / 90890-06786. The pump module is treated as an assembly that must not be disassembled, although filter, sender and electrical checks are covered.

Injector installation notes warn that an improperly lubricated O-ring can twist and break, causing a fuel leak.

Jet-pump procedures extend to intermediate-housing disassembly, driven-coupling work and shim placement. The direct-drive, single-stage axial-flow pump uses a reverse gate and manual five-position trim; steering, shift-cable and QSTS adjustment procedures address these controls.

YDIS Troubleshooting and Electrical Tests

YDIS Ver. 1.30/1.32 coverage explains Diagnosis, Diagnosis Record, Engine Monitor, Stationary Test and Active Test. Data Logger and the ECM Record Data Graph provide access to stored operating and fault data.

The diagnostic-code charts connect faults to component checks, while separate symptom tables address starting problems, unstable idle, poor acceleration and limited engine speed when no diagnostic code is detected. Yamaha recommends YDIS for ETV/TPS/APS troubleshooting because the dual analog meter can display only one diagnostic code at a time.

Component testing: Voltage, resistance and continuity checks cover ignition, charging, the oil-pressure switch, thermoswitch and thermo sensor. Further tests address intake-air and engine-temperature sensors, TPS, APS, the cam-position sensor, ETV relay, steering sensor and reverse sensor.

The ECM circuit diagram, ECM coupler layout and full Wiring diagram support circuit tracing and connector identification. Equipment references identify connecting kit 60V-85300-04 and version-specific YDIS CD-ROMs; detailed software operation is referred to the separate YDIS Ver. 1.30/1.32 Instruction Manual.

Model Differences and Control-System Limits

The FZR is configured for two riders; the FZS carries three and has a reboarding step. Their rear seats and handgrips are not interchangeable.

FZR/FZS ECM identification is 6AN-**. These models do not use the FX SHO cruise-assist or no-wake functions, and their ECMs are not interchangeable with the FX SHO units. The 649.5 mm (25.57 in.) FZR/FZS drive shaft is also longer than the FX SHO shaft and is not interchangeable.

Cable and hose routing views cover Starboard bow, Top and Port locations. Steering service includes an important limit: the handlebar bracket and board spring must not be disassembled, because this can affect OTS operation. Shift-lever disassembly is limited to the reverse sensor.

Workshop Precautions

Generator/drive-coupling instructions warn against gas-torch use and heat damage to the wiring harness; relay-testing notes warn that reversed battery leads can damage the main and fuel-pump relay.

Fuel-system safety notes address pressure release, jet-pump warnings require battery removal, and running the engine on land requires an adequate cooling-water supply. Follow the manual’s WARNINGS, NOTICEs, specified tools and torque procedures for work involving pressurized fuel, rotating machinery, hot components or electrical testing.

A Preview of Valve, Fuel-Pressure and Impeller Specifications

Cold valve-clearance specifications are 0.14–0.23 mm for the intake valves and 0.28–0.37 mm for the exhaust valves. Fuel-pressure measurement after engine warm-up uses a specified range of 345–370 kPa.

Jet-pump inspection data distinguishes the standard impeller-to-housing clearance of 0.35–0.45 mm from the 0.6 mm clearance limit.
