Avoid Propeller Cavitation by Using Stainless Steel

Avoid propeller cavitation by choosing stainless steel.

I have discussed what the benefits of using stainless steel for boat propellers are but now I would like to talk specifically about the concern for cavitation.

Another concern for boat propellers is cavitation.  You can literally feel cavitation by running your finger along the edge of a fragile propeller and feeling a pitted area.  This pitted area is cavitation.  It happens when damaged, unreliable, weak propellers try to convey excessive power through the propeller.  When this occurs, the extreme rotating speeds cause pressure on the inlet side of the blade dropping it into the water creating a vapor pocket which fails at transmitting force into the water.  The bubbles then concave releasing a shock wave that damages, stretches and strips away at the weak propeller.  The cavitation then dings, scratches, bends and initiates further harm to the propeller and boat accordingly.

When you choose stainless steel propellers the cavitation threats are avoided.  You do not have the same problems as you do with other materials.  The strength of the steel holds up under such bubbling, extreme water pressure.  The cavitation process is completely eluded.
