99 Johnson 115 prop size

I have a 1999 Johnson 115 that I need a lower pitch prop for. Anyone know what diameter it should be? Thanks

13 or 13 3/4.<br /><br />But you really need to start out finding your existing props' specs. and your actual WOT rpm.<br /><br />The prop has a # stamped into it which will be the base for the task.<br /><br />Then it's pretty easy to calculate your next prop - provided you know what you expect from it.
