End of First Season Checkup
At the end of the first season of operation, contact an authorized Mercury MerCruiser dealer to discuss and/or perform
scheduled maintenance items. If you are in an area where the product is operated continuously, year‑round, you should contact
your dealer at the end of the first 100 hours of operation or once yearly, whichever occurs first.
Getting Started—3.0 TKS
20‑Hour Break‑In Period
IMPORTANT: The first 20 hours of operation is the engine break‑in period. Correct break‑in is essential to obtain minimum oil
consumption and maximum engine performance. During this break‑in period, the following rules must be observed:
•
Do not operate below 1500 RPM for extended periods of time for the first 10 hours. Shift into gear as soon as possible after
starting and advance the throttle above 1500 RPM if conditions permit safe operation.
•
Do not operate at one speed consistently for extended periods.
•
Do not exceed 3/4 throttle during the first 10 hours. During the next 10 hours, occasional operation at full throttle is
permissible (five minutes at a time maximum).
•
Avoid full throttle acceleration from idle speed.
•
Do not operate at full throttle until the engine reaches normal operating temperature.
•
Frequently check engine oil level. Add oil as needed. It is normal for oil consumption to be high during the break‑in period.
After Break‑In Period
To help extend the life of your Mercury MerCruiser power package, follow these recommendations:
•
Ensure that the propeller allows the engine to operate at or near the top of the specified WOT RPM range. Refer to
Specifications
and
Maintenance
.
•
Operate the engine at 3/4 throttle or lower. Refrain from prolonged operation at wide‑open throttle RPM.
•
Change the engine oil and oil filter. Refer to
Maintenance
.
NOTE: If the boat is equipped with a gauge that displays scheduled oil changes, do not reset the gauge after this oil
change.
•
Change the transmission oil and filter. Refer to
Maintenance
(ZF transmission models).
