There are many important factors that must be considered during the search for a replacement propeller for a boat. This is because boat propellers come in a wide range of sizes, styles and materials. If you already know the type and size of blades you need, then all you need to do is choose the material. Some people claim that stainless steel blades are better than aluminum boat propellers and vice versa. In order to make the right decision, you need to analyze the pros and cons of each type of boat propeller. You must weigh the benefits of using certain propellers against their disadvantages.
Advantages of Aluminum Boat Propellers
These propellers are very popular because of their affordability and high performance under different types of operating conditions. Another benefit of aluminum props is that they are very light. This makes them very easy to repair when they break or malfunction.
Disadvantages of Aluminum Boat Props
Aluminum is very light and can flex when the boat pushes extremely high rpms, and this can reduce the pitch of the prop. These blades are also known to cause more drag because they are normally thicker than stainless steel props. If you normally use your boat in sandy conditions, aluminum props may not be suitable.
Advantages of Stainless Steel Propellers
An in-depth analysis of boat propellers in the market today indicate that stainless steel props are the most popular. These blades are thinner and stronger, meaning that they neither flex at high speeds nor cause excessive drag. They can also be used in abrasive environments such as shallow and sandy waters.
Disadvantages of Stainless Steel Props
Stainless Steel is more expensive than other materials, and the blades of the props are sometimes harder to repair when damaged. Their weight is also a disadvantage because these propellers can only be used with powerful engines.
All said and done, the needs of the users will determine the most suitable type of propeller to purchase. Those who are not interested in power can purchase aluminum props. However, those who are interested in power or high performance should purchase stainless steel props. Pricing, durability and overall use are also important factors to consider.
