Oil consumption is greatly dependant upon engine speed, with
consumption being highest at wide‑open throttle and decreasing
substantially as engine speed is reduced. It is not uncommon 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.
1. With the engine at normal operating temperature and engine
speed at idle, check the oil reservoir sight tube.

2. The oil level is correct if the oil in the tube is level with the
center of the reservoir split ring.
IMPORTANT: Do not overfill engine oil.

NOTE: If the engine is not operated for a period of time (several
days or longer), a certain amount of oil may drain from the reservoir
back into the engine. When the engine is started this oil will be
pumped back into the reservoir.

IMPORTANT: Check oil level with sterndrive unit in the full down/in
position.
1. Place the sterndrive unit in the full down/in position.
2. Check the fluid level in the trim pump reservoir. The level
should be between the "MIN" and "MAX" level marks on the
reservoir.
