Professionally demanding documentation addresses the complete mechanical and electrical architecture of these high-performance watercraft. The manual encompasses examination of engine construction including magneto systems, ignition timing procedures, and spark plug specifications. Verification procedures are included for rotary valve clearance, crankshaft alignment at multiple journal positions, and bottom-end bearing inspection with established tolerance measurements.
Cooling system flushing and lubrication protocols document the water intake configuration from jet pump pressure zones and the routing of fresh water through cylinder head assemblies. Testing procedures are addressed for fuel system pressurization, carburetor synchronization on twin-configuration models, and acceleration pump verification using specialized gauge equipment. Special procedures are addressed for the RAVE (Rotary Adjustable Variable Exhaust) system found on 787 engine variants, including diaphragm spring preload adjustment and guillotine clearance limits relative to cylinder bore diameter.
Repair information is provided for the electrical subsystems including the digitally encoded security system (DESS), multi-purpose electronic module (MPEM) with RPM limiting logic, and diagnostic beeper codes for identifying component failures. The document includes trigger coil and ignition coil testing procedures, stator resistance measurement protocols, and the complete sequence for adjusting ignition timing using degree wheel positioning relative to top dead center. Wiring diagram references support troubleshooting of charging system voltage regulation, starting system solenoid operation, and battery activation procedures.
The propulsion system section documents torque specifications for jet pump assembly fasteners to ensure proper gasket seal integrity. Impeller shaft bearing installation, wear ring clearance verification using feeler gauge measurement, and reverse gate linkage adjustment are comprehensively detailed. Drive shaft boot examination, impeller condition assessment, and ventilation seal verification procedures support performance diagnostics and component replacement sequencing.
| Topic | Documentation Scope | Component Coverage |
|---|---|---|
| Magneto System | Removal, disassembly, and reinstallation | Armature plate indexing, generating coil replacement, trigger coil alignment |
| Top End Assembly | Cylinder head, piston, and valve service | Combustion chamber volume measurement, ring compressor installation, gasket thickness selection |
| Bottom End Rebuild | Crankshaft and counterbalance shaft | Deflection measurement between centers, connecting rod straightness, bearing preload verification |
| Rotary Valve | Timing verification and clearance testing | 45-degree feeler gauge method and solder compression technique |
| Exhaust System | Tuned pipe and muffler removal/installation | TIG welding repair procedures, water injection fitting calibration |
Storage procedures document engine drain tube inspection, antifreeze circulation through cooling system passages with hose pincher application, and PTO flywheel lubrication at grease fittings. Battery storage recommendations address hydrometer specific gravity testing with temperature correction factors, and charging procedures for deeply discharged cells requiring extended low-current application.
The manual documents torque specifications for the engine support screws to maintain jet pump alignment without exceeding shim thickness limits. Fuel filter bowl inspection addresses water contamination detection, and carburetor cleaning with heavy-duty solvents specifies O-ring and diaphragm removal prior to immersion. The MPEM operation section describes automatic power shut-down timing, neutral position switching logic, and RPM limiter threshold values for forward and reverse gear positions.
| System | Procedure Reference | Specification Detail |
|---|---|---|
| Oil Injection | Pump cable synchronization with throttle position | Flow rate measurement at 1500 RPM with counterclockwise rotation |
