Why select Kruger & Sons Propeller?

We are staffed by propeller repair professionals, with two generations of developed repair and manufacturing skills.
Our computer aided pitchometer is an instrument that gives us the most accurate information available to enhance your propellers accuracy.
Propeller repairs and modifications using our computer aided pitchometer creates a detailed report of the propellers condition. Both us and the boat owner have a clear future reference of the propeller(s) dimensions.
Once desired performance is obtained, future repair or manufactured replacement can match an individual propeller data on file.
On custom designed propellers, the precision MRI system is required to fully integrate sophisticated design and allows us to accomplish a repair that meets the original design. The MRI system can recognize and apply original design data supplied by the original propeller manufacturer.
On both custom and standard series propellers, the MRI provides data from which we can address performance issues with the customer. Properly restored or pitch corrected propellers can synchronize propeller loading, improve speed and fuel economy and minimize vibration and noise.
