ABOUT PROPELLER CACULATIONS
Please fill in this information list carefully, because the data stated by you gives us the basis for the propeller calculation.

We point out that a calculated propeller is always only a recommendation! A guarantee that the calculated propeller is the "perfect one“, cannot be given since even the computer calculation is only theoretical at the optimum. Only a carefully timed and controlled test run will show the actual results.

If the performance does not correspond to the expected optimal conditions, an appropriate revision should be made to the propeller. This may involve changing the pitch or the diameter or (seldom) both.

Consequential expenses like Hauling, Installing and Freight charges are not paid by VARIPROP USA
