PropTech provides all conventional repair services for propellers that are damaged but serviceable:

	Welding of bronze, NiBrAl, and stainless  to repair cavitation burns and impact metal loss,
	Reforming damaged blades to conform to the original design,
	Changing blade camber and section pitch distribution for enhanced performance,
	Changing the average pitch to conform to a performance requirement,

Diameter reduction,

Refinishing to factory finish or better,

Mass balancing

        Tuning propellers, at  PropTech, means the following:

Measuring the surfaces of each blade to create an exact model of the current state of the propellers,

Calculating (via the PropScanTM  software modeling package), from boat weight and geometry, power parameters, gearbox ratio, and specified and actual WOT speeds and engine turns, the optimum propeller diameter and pitch for the client,

Re-pitching the propellers to conform to this optimization,

	Retaining the original design camber, or improving it to enhance performance,

	Extracting the underlying design, and bringing each point on the blade surfaces into that design and into tolerance for the ISO class (Class 1 or Class S) desired by the client.

This tuning process, and only this process, gives our clients a matched boat-power train-propeller system that operates at maximum efficiency and performance and minimum vibration and fuel consumption.
