_Quick Pick Propeller Guide_________
According to your manual's recommended
WOT RPM range for your motor.....
- RPM's too high? (Move up in pitch)
- RPM's too low? (Move down in pitch)
- RPM's just right? (Stay with the same pitch)
 Note: For every 2" of pitch will raise or lower your
RPM's by 400(approx).

WOT RPM's for OMC Motors
Check your manual or the list below for your motor's WOT RPM range.
At WOT your boat should ideally be running at the upper end of the
range for maximum performance. Water sports or extra people on board
may require a drop in pitch to meet the WOT RPM requirements.
