If anyone has a 175 hp Johnson, please tell me your prop size and pitch. I bought a used boat with a model J175EXEDB outboard and want to by a spare prop. There is no marking on the current prop that I can see. It has 3 blades.
there is not a standard prop size for a motor because every boat is different. there probably is some markings somewhere on your prop, take it to a boat parts store and I am sure they can help you out.
