Checking Fluid Levels
CRANKCASE OIL
The engine crankcase oil level must be checked at the intervals
specified in the
Maintenance Chart.
NOTE: Oil consumption is greatly dependant on engine speed.
Consumption is highest at wide‑open throttle and decreases
substantially as engine speed is reduced. It is common for big
block, high‑performance engines to use up to one quart of oil in
one to five hours if the engine is operated continuously at the
upper end of the RPM range.
Stop the engine. Allow approximately five minutes for the oil to
drain into the oil pan. The boat must be at rest in the water.
1. Remove the dipstick, wipe it clean, and install the dipstick.
