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 con-
tacted 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.
