[THEFERMANATOR]

I don't have alot of 4 stroke experience(I'm a 2 smoker kind of guy), but everybody I've talked to about propping them said you want them with a light to average load to spin right up to the max rated RPM, or an extra 100. My skiff propped from the factory spun up to almost 6200, and it's rated range is 5000-6000. I propped it so it spun up to 5600 and it just felt doggy, and top end was a bit low, repropped to hit 5900-6100, and it's a completely different boat. The 15" prop will allow you to plane at slower speeds and lower rpm's, hold better in a chop without blowout, and normally pull heavier loads better, but you do lose some top end mph. I've always run a large diameter on a boat that could see rough water just for the better bite and hold as it was not that often that I was able to run hammer down in a chop, so I enjoyed the advantages for the few disadvantages.
