What our service work and the manufacturer documentation say about keeping this model running.
Inspect the jet intake, impeller and pump area for debris, impact damage and abnormal clearance symptoms, using manufacturer limits for all measurements. Check cooling and exhaust hoses, clamps and flushing passages for leakage, blockage or deterioration. Inspect spark plugs, fuel-system components, wiring connectors and battery condition and review stored diagnostic faults where supported. Check engine mounts, hull penetrations and pump attachment for secure condition and signs of water leakage. Verify throttle, steering, neutral or reverse device, emergency stop and warning functions according to the craft configuration. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Carry specified spark plugs, fuel-filter or strainer items, fuses, approved seals and gaskets, hose clamps and common electrical service parts.
