Stainless Steel Propellers for Your Boat: Advantages and Disadvantages

Boat propellers are usually made from stainless steel or aluminum. Stainless steel propellers have a few advantages and disadvantages when compared to those that are made from aluminum. This article will...

Advantages

One of the first advantages of stainless steel propellers is flex. Aluminum propellers will flex whenever the boat is traveling at higher speeds. This will cause them to suffer a loss in performance. Stainless steel propellers are more rigid, so they will perform much better.

Another advantage of stainless steel propellers is their durability. Aluminum propellers can easily be damaged by rocks and other objects in the water. Stainless steel propellers can withstand more damage. They will also last longer in salt water than aluminum propellers.

Disadvantages

Stainless steel propellers have a few disadvantages. One of the first is cost. Aluminum propellers are much cheaper than the stainless steel variety. They usually come standard with most outboard motors. Stainless steel propellers typically cost several times as much as the aluminum variety. It will cost more to re-cup them too.

Another disadvantage of stainless steel propellers deals with damage. As mentioned earlier, these propellers are rigid and will withstand damage from rocks and other objects in the water. However, if you hit an object hard enough, stainless steel propellers may damage the lower unit of your boat. This will cost a lot of money to fix. Aluminum propellers will usually become damaged themselves without damaging your boat if you hit an object too hard.

One of the final disadvantages of stainless steel propellers is their weight. They are significantly heavier than their aluminum cousins. This extra weight may lead to a clunking sound whenever you shift into gear. Also, stainless steel propellers may also damage the gears if the idle on your motor is set too high. Therefore, you will need to set the idle to the lowest possible RPMs.

These are some of the advantages and disadvantages of stainless steel propellers. They are more rigid in the water, so they will give much better performance than aluminum propellers. However, instead of being damaged themselves, stainless steel propellers may damage the lower unit of your boat if you hit an object hard enough. You will also pay a lot more money to buy one of these propellers because they usually cost several times as much as the aluminum variety.
