Model-specific OEM reference checks
F300 DEC 35: OEM-published Engine displacement reference is 4.2 L. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
F300 DEC 35: OEM-published Cylinders reference is 6. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
F300 DEC 35: OEM-published Prop-shaft power reference is 300 hp. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
F300 DEC 35: OEM-published Power rpm reference is 5500 rpm. Measurement/evaluation on the same configuration should use this published value as context; obtain any service tolerance from the VIN/serial-matched OEM procedure.
Diagnostic entry symptoms
Failure to reach target WOT rpm / power loss
Overheating or cooling-water flow issue
Low charging output or unstable idle
Measurement and test approach
Compare full-throttle WOT rpm with the manufacturer range; record throttle opening and boat-load condition to separate propeller loading from fuel/ignition/compression faults.
Verify engine-oil capacity, charging amperage, spark plug and fuel-octane requirement against the OEM reference in this model record.
Root-cause discrimination
If WOT is low, first separate propeller pitch/boat load from engine air-fuel-ignition/compression output.
DTC / SPN / FMI context
When ECM faults are present, preserve rpm, trim, temperature and load condition.
Post-repair verification
After dock checks, verify idle, mid-load and WOT range plus cooling and charging behavior in a controlled on-water test.
Electrical and network
F300: Evaluate ECM, gauge/command-link, trim and charging system together.
Sensors, actuators and observation points
F300: TPS and engine rpm.
F300: MAP/intake temperature and fuel injection.
F300: Cooling-water/engine temperature.
F300: Alternator/charging output.
F300: Trim/tilt position.
F300: ECM fault/freeze data.
