Stainless steel propellers offer greater performance and durability than their aluminium counterparts. The stainless steel construction of props enhances overall boat performance and offers long-term dependability.
Here we take a look at general propeller design and weigh up the pros and cons of stainless steel propeller choices.
Propeller size selection
When determining the propeller size, such as 13 x 18, the first number confirms the diameter of the propeller and the second number is the pitch that the propeller blades are set at.
The pitch is the most important number of these two numbers as the diameter is usually predetermined by the propeller manufacturer and is based on the size and series of the particular outboard motor it will be used in conjunction with.
