Is there that many to choose from?
There are 5 basic sizes,7,8,9,10,11 each size has 4 - 7 designs.
If you run the boat empty a 10" is probably the one you want.
A 10 comes in 7 choices.Assuming a healthy motor and correct setup a cheap 10" will probably work.
But it is important that the motor be able to operate within its wot rpm range.
To get us started if you get us the present size and the lightly loaded wot gps speed we may be able to get an idea how your setup works.
without that info we can't tell what you may need.
