There are a number of factors to be considered when determining prop size. Diameter is usually limited by the space available below the hull, and pitch is related to shaft RPM (among other things). In short, the biggest prop may not be the best. Look at some of the propeller manufacturers' websites, where they have lots of technical information to help you determine what might work for your boat.

Largest prop for a Newport 30
I am in the process of re-powering my Newport 30 MkII. I will be installing a 180A electric motor on her and will install a new 3 blade prop to take advantage of the greater efficiency of the electric drive. What is the largest prop that has been installed on a Newport 30?
As an aside, the Atomic 4 came out in 4 hours. It still runs well.
