400 rpms would be roughly the difference overall. The 14" will have more thrust capability due to larger surface area.
The big thing to watch out for here would be hub size. The 13" diameter is usually the smaller hub (4" I believe) which fits many motors from 70hp up to 130hp, and the 14" diameter is roughly a 4-1/2" hub or 4-3/4" hub which fits 150hp up to roughly 225 or so depending on brand.
I used algebra today... Taking a course so I'm looking at a lot of higher algebraic concepts... Want to hear about it? Fulfill your day?
