30" 4 blade prop for 6.5hp honda

[Zion]

Any suggestions on where to buy a 30"-4blade wooden prop for a honda 6.5hp engine with a 5/8" shaft?
I'm building a super light 12' jon boat for bow hunting in a marsh.
Since I have a small vertical shaft engine I'd prefer a fan drive to a mud motor.
I'd like to get a 4 blade to help quieten it down some.
Don't wont to spend a months pay on it.
If I knew what pitch I needed for a 6.5hp 4 stroke engine I'd get zinger prop to make it.
The price is right just don't know what I need.
