After Break-In Period

To help extend the life of your MerCruiser power package, the
following recommendations should be considered;
Use a propeller that allows the engine to operate at or near the top
of the maximum RPM range (See "Specifications" section) when
at full throttle with a normal boat load.
Operation at 3/4 throttle setting or lower is recommended. Refrain
from prolonged operation at maximum (full throttle) RPM.

End of First Season Checkup

At the end of the first season of operation, an Authorized MerCruiser
Dealer should be contacted to discuss and/or perform various
scheduled maintenance items. If you are in an area where the
product is operated continuously (year-round operation), you should
contact your dealer at the end of the first 100 hours of operation, or
once yearly, whichever occurs first.
