I have some experience in a P-III with a 200 efi. I was looking at buying one when I bought my classic and took several test rides as well as fished out of one several times over the years. The 25″ temptest as BCB stated is just too much prop for that hull and a 2.5 liter efi. The 23 temptest or if you can find one of the rare 24 temptest you could try that as well. You will be much happier overall with the boat after you downsize the prop. It will do everything better and you wont loose very much on top end. Chris CoupelPaulina, La.Chris CoupelPaulina, La.
