| *THESE RPM VALUES MAY VARY ACCORDING TO HOW YOUR BOAT ALLOWS THE PUMP TO LOAD | ||||||||
| HORSE POWER REQUIREMENTS ARE AT THE PUMP SHAFT | ||||||||
NOTE: A Good Rule of Thumb when changing over to a Precision Billet or Aggressor Impeller is to drop one full cut in order to keep your RPM's the same. This is due to the Impellers aggressive load and flow volumes.
