2003 johnson 115hp 2stroke 20" , prop size ?

[OneLuv1979]

I Have a 2003 Johnson 115hp 2stroke , and need to know how many spline the lower unit is ....
I can check it when i drive to my storage but need a larger prop for the weekend and want to order it now ...
I ordered a prop for my 1999 Johnson 90hp 2stroke which was a 15 spline , i ordered the prop from iboats when it arrived it didnt fit properly ...
I ended up paying a restocking fee when there computer sold me the wrong prop ....

Is there anything else i need to measure ?

There are two stroke, 115HP, 20" 2003 motors with 13 spline propshafts and with 15 spline propshafts; it depends on the model.

What is the number on your current propeller?
