CRUSADER MASTER WARNING/ALARM SPECIFICATIONS - 2007 - SN 671344 and higher
**IMPORTANT NOTICE: Crusader engines incorporate an RPM “MAX GOVERNOR” in order to prevent the engine from over-revving.
Engine operation above the Maximum RPM listed will appear normal, but will not exceed the (**MAX Governor) RPM listed. This is not
recommended. If the engine is operating above the maximum RPM listed, a higher pitched propeller would be required to lower the engine
maximum RPM to the Preferred RPM listed in the chart above.
NOTE: FOR NEW BOAT PROPPING, IT IS RECOMMENDED THAT OEMS PROP TO THE MAXIMUM RPM LISTED.
