Detailed System Documentation

The identification pages separate the configurations before repair information or parts are selected. For 2008, SXT1100A-G and B-G identify AR230 HO configurations, C-G through E-G identify SX230 HO configurations, and F-G identifies the 232 Limited. For 2009, A-H and B-H cover AR230 HO, C-H through F-H cover SX230 HO, G-H is the 232 Limited S, and H-H is the 232 Limited. The corresponding AL-H through HL-H designations appear in the same table. Engine serial coverage begins at 6P6 serial 1010101 and 6AB serial 1000001 for California models.

Starting primary IDs are listed by configuration. With SXT1100 as the model-code prefix, the 2008 entries are A-G / F2A-731001, B-G / F2A-741001, C-G / F2A-751001, D-G / F2A-711201, E-G / F2A-761001, and F-G / F2A-771001. The 2009 entries are A-H / F2A-711601, B-H / F2A-721601, C-H / F2A-732101, D-H / F2A-742601, E-H / F2A-752401, F-H / F2A-761601, G-H / F2A-771701, and H-H / F2A-781401.

The engine information separates the standard 6P6 build from the California-specification 6AB build. The 6AB sections document its catalyst-equipped exhaust, high-rise cooling-water outlet hose, exhaust-temperature monitoring, revised sensor and hose layouts, and separate ECM identification. Yamaha identifies the 6P6 and 6AB ECMs as non-interchangeable, which matters when diagnosing faults or ordering electrical parts.

The base manual has nine numbered chapters: General Information, Specifications, Periodic Inspection and Adjustment, Fuel System, Power Unit, Jet Pump Unit, Electrical System, Hull and Deck, and Trouble Analysis. The 2009 supplement updates identification and specifications, fuel, electrical, and hull/deck material for the later configurations. Although the base publication also carries SR230 information, the 2008–2009 supplement coverage is the four model families listed above.

Disconnect the battery, ventilate the engine compartment, and relieve fuel-system pressure before working around electrical components or gasoline lines. Use marine-service precautions around rotating machinery, ignition-voltage testing, hot exhaust parts, and pressurized fuel.

Factory Procedures, Diagnostics, and Service Data

Assembly sections use exploded views, removal and installation charts, inspection notes, service points, and component-specific tightening data. The power-unit material reaches internal engine repair rather than stopping at routine maintenance, covering the oil tank and pump, reduction drive, flywheel magneto, starter clutch, valve train, crankcase, rotating assembly, thermostat, and cooling-water hoses.

Jet-pump repair runs from the intake grating and pump unit through the reverse gate, deflector, impeller, drive shaft, clean-out ports, and intermediate-shaft housing. Bearing, oil-seal, and shaft procedures are paired with inspection limits and special tools. Hull and deck chapters address engine-compartment layout, ventilation and cooling, steering and remote controls, throttle and shift cables, hatches, seating, windshield, through-hull fittings, drains, gunwale components, and FRP construction and care.

Electrical diagnosis covers ignition spark and peak-voltage checks, coil and sensor tests, starting-motor inspection, charging-system testing, fuel-control checks, switches, relays, and model-specific meter-panel wiring. The Yamaha Diagnostic System section explains software setup and connection, Diagnosis and Diagnosis Record functions, Engine Monitor, stationary ignition-coil/injector/fuel-pump tests, active cylinder-drop testing, Data Logger use, ECM identification, and error-code and trouble-analysis charts.

Representative visual references include 6P6 and 6AB cable-and-hose routing views, ignition and fuel-control wiring diagrams, starting and charging schematics, meter-panel rear views, fuel-pump and throttle-body exploded diagrams, and impeller/drive-shaft assembly views. Special-tool references identify the Yamaha YDIS kit (LIT-YDIS1-30-00) and communication cable (60V-WS850-00-00), vacuum synchronizer (YU-44456), fuel-pressure gauge adapter (YW-06842 / 90890-06842), peak-voltage adapter (YU-39991 / 90890-03172), and drive-shaft holder (YB-06151 / 90890-06519).

Factory tables cover torque values, fluid capacities, compression and valve data, camshaft and piston clearances, crankshaft and bearing limits, fuel-pressure testing, oil-pump inspection, electrical resistance and peak-voltage checks, sensor and switch thresholds, cable adjustments, and hull and jet-pump service limits.

The camshaft section warns against rotating the crankshaft during camshaft installation and requires correct timing marks and tensioner orientation; an incorrect setup can cause engine damage or improper valve timing. Fuel-system notes call for cutting crimp clamps before hose removal and lubricating injector O-rings before assembly, since damaged hoses or twisted O-rings can leak. The intermediate-shaft procedure also directs the mechanic to mark shim locations before disassembly so the factory arrangement is restored during reassembly.
