If you want your boat to have more speed and better load carrying capacity, then you must have good propellers. Outboard propellers can now be purchased online. There are many propeller choices that you can find online. There are some websites that offer discounts to outboard propellers.

It would be helpful if you understand terms like pitch, diameter, blade thickness, cavitations, cupping slip, ventilation, and rake. These terms will be helpful if you are buying outboard propellers. You also need to pay attention to the propeller material. The best material for outboard propellers is aluminum. They are very durable. Stainless steel propellers are also a good option and has a long life. The hydrodynamic efficiency of stainless steel is also greater.

The boat will also be pulled sideways if you have high pitch propellers. High pitch propellers well pull the boat sideways.
