The computerized Prop Scan was specifically designed to inspect the accuracy and precise hydrodynamic form of Australian, Canadian and US Navy propellers.

The accuracy and form or shape of a propeller blade section as it slices through the water determines the ultimate thrust and performance of any vessel.

Using Prop Scan technology a Prop Scan Technician will measure your propeller free of charge, check the accuracy against the ISO 484 International Standards and determine the section form of your propeller.

To optimize your propeller your Prop Scan Technician can then correct any accuracy problems, apply the correct section form and also tune the pitch of your propellers.

An accurate ‘Prop Scan’ propeller with the correct section form and pitch will always out-perform a standard propeller. You will get fuel savings, increased boat speed, reduced vibration, correct engine RPM and correct engine loading.

     ISO Propeller Standards      Who uses Prop Scan  

The International Organization for Standardization has produced a standard
(ISO 484/2) that defines the tolerances for marine propellers.

All marine propellers can be placed in a class based on the ISO 484/2 standards.

ISO 484/2 Accuracy Classes
Very High Accuracy
High Accuracy
Medium Accuracy
Wide Tolerances

Due to Prop Scan's high levels of accuracy it is now possible to repair a propeller to an accuracy level twice the accuracy of  Class S. We call this Class 0

Prop Scan is used extensively in the marine industry worldwide to repair and modify propellers to their peak performance.

 Prop Scan Success Stories

 We have helped establish successful propeller repair businesses worldwide. The reason for their success is simple:
Our equipment, training and support is the best in the world.

 Speed Increase of 5 knots

Both propellers were fine tuned with Prop Scan and the pitch was reduced by ½" to 19". The boat was returned to the water, where sea trials produced a maximum speed of 20.2 knots at 2750 RPM. This was an increase of 5 Knots.

 Vibration's Gone

The boat ran so smoothly, u-boat replica I didn't know it wasn't smooth before. I picked up 1 to 1½ Knots on Saturdays 3-4 Ft seas. This was on a 44 sea ray exp. bridge, running 350 cats.

Decreased fuel consumption

If I didn't achieve one thing in performance, replica watches the difference in sound & smoothness was worth it. I can't believe how much quieter the boats runs now. As for performance: I picked up almost 1 knot in my cruise speed at the same rpm's as I ran before. The best part is I decreased my fuel consumption by over 15%
