not meet Mercury Marine battery requirements.
6.2L MPI Engine Specifications
NOTE: Performance specifications are obtained and corrected in accordance with SAE J1228/ISO 8665 Crankshaft Power.
All measurements are taken with the engine at normal operating temperature.
RPM range is measured using an accurate service tachometer with the engine at normal operating temperatures.
Oil pressure must be checked with the engine at normal operating temperature.
NOTE: Oil pressure specifications are for reference and may vary.
IMPORTANT: Do not mix spark plug types in an engine. All spark plugs should have the same part number.
