Notes on Engine Specifications

• Performance specifications are obtained and corrected in accordance with SAE J1228 (crankshaft power) and ISO 8665
(standard 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.
• 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.

IMPORTANT: It may be necessary to adjust the oil levels depending on the installation angle of the engine and the type of
cooling system—the heat exchanger and the fluid lines, on the engine.
NOTE: Measure the oil level with the boat in the water.
