Hello. My name is Tan.

Aluminum 3 blade 14.5 X 19 P/N 832830A45 , stainless steel 14 X 19 P/N 16316A46 .

Is there anything else I can help you with on your prop question?

What is the same in a 4 prop?

Aluminum 4 blade 14.5 X 19 P/N 832830A45, Stainless steel 14 X 19 P/N 825900A48

When you go to multiple blades the pitch is still calculated the same. The way they calculate pitch is how much it pushes the boat forward in one revolution.
