What size prop for a mini moto engine

I am in the process of buildin small hovercraft powered by two mini moto 49cc engines. I am just confused of what prop size they could spin with ease and produce alot of thrust. I am thinking something in the region of 18 - 20 inch prop but it may be too large or too small. The engines are around 3hp.
