affect performance and could  also seriously
damage the  motor. Engine  speed depends
on the propeller size and boat load. If engine
speed is too high or too low for good engine
performance, this will have an adverse effect
on the engine.

pellers chosen to perform  well over a range
of applications, but there may be uses where
a  propeller with  a  different pitch  would  be
more  appropriate.  For a  greater  operating
load, a  smaller-pitch propeller  is more suit-
able as it  enables the correct engine  speed
