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 that the
propeller does not underload or overload the engine.
Propeller Overloading, resulting in low RPM's 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.
NOTE: Running your boat in shallow water can cause sand and silt to be
pulled into the cooling system. This can create excessive water pump wear and
may clog the water passages in the engine. Heavy weed growth in the water
can plug the raw water strainer and oil coolers and cause engine damage. There
is a raw water filter located near the rear of the engine that filters the water
before it goes into the transmission cooler and then the engine. Check this
every time you use the boat to make sure it is not clogged.
