If you’re upgrading from a three-blade propeller to a four-blade propeller, remember that many four-blade propellers generally turn 50 to 100 RPM less than a three-blade propeller with the same pitch.
Mercury Reduced the diameter slightly to keep the RPM's up.

Kyle - I was thinking of moving my motor up one hole and to see if it would help. I think you may have convinced me to give it a try.
