Getting Underway
Break In Procedure
Make sure all your passengers are properly seated before starting the break in procedure. After the engine is thoroughly warmed up and you have driven the boat into a large open area, advance the throttle to wide open until the maximum rpms are reached. DO NOT exceed 5,000 rpm. Reduce the throttle to
CAUTION Follow these procedures only when conditions are such that you can drive the boat safely. DO NOT attempt to break in an engine by letting it idle at the dock.
Propeller Selection
The maximum rpm of the engine at full throttle under normal load conditions can be controlled by propeller pitch, diameter and design. It is essential the propeller does not underload or overload the engine.
Propeller Overloading, results in low rpms at wide open throttle will give poor performance, poor fuel economy and eventually result in engine damage.
Propeller Underloading, if operated with a propeller that has too little pitch or diameter, poor performance will result.
