POWERFIN WEIGHTS

       The weights posted below are approximate for new blades and hubs only. There have been minor design variations over the years that have changed the weights of both the blade models and the hubs. Older blades are slightly lighter. Older hubs are heavier.

To find the weight of your propeller, take the weight listed for the blade style at the diameter you have times the number of blades plus the hub weight.
 

BLADE WEIGHTS

Weights are per blade before balancing operations. Weights are given in GRAMS / OUNCES.
