Why Select an MRI Shop? The MRI shops are staffed by propeller repair professionals, with years of developed repair skills. The MRI is an instrument that gives the shop accurate information to enhance their repair capability. Repair with MRI creates a detailed report of propeller condition. Both the shop and boat owner have a clear future reference. Once desired performance is obtained, future propeller repair or manufacture can match an individual MRI file. On full custom propellers the precision MRI system is necessary to fully integrate sophisticated design and permit repair. The MRI system can recognize and apply original design data supported by Federal Propeller. The MRI can also interpret to the original inspection reports typically supplied with full custom propellers. On both custom and standard series propellers, the MRI provides information from which the propeller shop and customer can address performance issues. Properly restored or corrected propellers can: Synchronize propeller loading Improve speed Improve fuel economy Minimize vibration Minimize noise.
