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.

The durability of stainless steel is one of many reasons the marine industry uses it for boat propellers.
Today we are attending the Sunseeker Boat Show in Southhampton, United Kingdom. I am easily impressed by the amount of attractive and exceedingly expensive options there are on boats today. It is literally the same as living in Beverly Hills, California but taking those mansion amenities and applying them to a boat. It is beyond my expectations and the way technology and materials have advanced, the boat makers are choosing better materials for the options. One very noticeable, essential option, the boat propeller, has followed in this same way of thinking. The majority of the boats are not displaying plastic or brass propellers anymore but rather exhibiting stainless steel boat propellers.
This type of metal has a wide array of benefits over other materials. One of the most predominant benefits is the longevity of the metal.
Plastic tends to change shape, break and fray when used as a propeller. It does not have the same damage resistance traits as stainless steel. It can’t compete. This is a major problem on your maintenance and upkeep fees. For example, if you look at the water your boat glides through a numerous amount of obstacles may appear. You have to maneuver through the debris, weeds, and sometimes disposed trash before reaching open, clean water. With a plastic propeller, the material that comes into contact with it may destroy or damage your boat. This becomes an extremely expensive problem. If you choose stainless steel then the chances of any cracking and damage from occurring reduces significantly.
