A propeller is a type of fan that produces thrust from its rotational motion. Stainless steel or aluminum is the two main ingredients used to make the boat propellers. In the recent times, the steel propellers are preferred more over the aluminum ones. There are both some benefits and problems in using them. The first advantage of the stainless steel boat propellers is that it is more rigid than its aluminum counterparts. The aluminum varieties being suppler tend to bend if the boat has gained a high velocity. The performance of the ship is disturbed a lot for this. Due to the inelasticity of the steel propellers, their performance is not hampered under any circumstances. Steel boat propellers last longer than the aluminum versions. Aluminum propellers are prone to damages in sea water from rocks or any other hard substances. The stronger steel ones can resist the collision forces from these substances more. Also, the salt content in the sea or ocean water can cause less damage to the steel ones than the aluminum propellers. There are some negative points about the steel boat propellers. Aluminum propellers are cheaper than the steel propellers. The steel propellers are charged several times more than the aluminum varieties. Also, the cost of maintenance for the steel versions is more too. The boat with the steel propellers is less prone to damage as already mentioned. But if the collision is really hard then the aluminum propellers will itself break without damaging the ship. The steel propellers in such cases cause great harm to the sip and it costs a lot to bring the ship back to its old shape. The weight of the steel propellers is much more than the aluminum ones. If the motor is kept idle for a long time, the steel propellers may damage the gears and so the motor should be set to a minimum RPM all the time.

The performance of the ship is disturbed a lot for this. Due to the inelasticity of the steel propellers, their performance is not hampered under any circumstances. Steel boat propellers last longer than the aluminum versions. Aluminum propellers are prone to damages in sea water from rocks or any other hard substances.
