Model Boat Propeller

What size propeller should I have on my model boat?
I have a 1.2 meter model boat with a 1.5 horsepower petrol engine in it. It weighs about 7kg. It is 1 foot wide the stern. It is a model of a bat boat, (which has a planing hull). It has a draft of about 3 inches.
What size propeller, what pitch and how many blades should i have to achieve it max potential speed.
If any other info is needed I can supply you with it.
Thanks
use this to calculate propeller size
