Usually a reputable prop dealer will let you test as many sets as you need to. You only buy 1 set. As long as they are not damaged, you just keep trying different ones until it gets dialed in. If you damage one, you bought it. Check around your area.

At BBLADES we offer a prop test program. I don't know of any other program like it in the country. We send out a new or like new propeller for a fee of $45. There are no strings attached to purchase anything. This is strickly a learning process. to determine what props suit your needs and the boats demands.
Call us if we can help. We ship all over North America.
