well I have had 3 different props on my V20, When it was a I/O it had a 15 3/4 X 15 and was pretty perfect!

Then Iconverted to a 175 yamaha and I put a 14 1/4 X 17, even though it was a good prop, I never was able to get to my 5500 RPM, but I got 30 to 33 for curz and toped about 38 or so with a 5100 rpm
I was also getting some spin when takeing off.

I just called a local prop shop and had a long talk about were I wanted to be. I now have a 15 1/4 X 15
I get 5500 RPM now and I get outn the hoe fast!! with no planing time!
I have lost about 5 mph off the top end. But this thing performs great now and I am happy as $hit!!!!

As for you I bet you will be good with what most run which is a 14 1/4 X 17

when you go from 17 to 15 you will get more RPM on the top end.
when you go 15 to 17 you get less RPM on the top end

good luck!! Call a local prop shop tell them what you have and what you want, They will help you match your prop with in one size, and if you get from them they will let you use it to try, and if you want different they will trade, as long as you no bang it up like CB did to mine!!

I just had to!! ;)
