I have a 23 High 5 Plus, and I will run it on a Puma or Cougar with a 250, for a play prop for kids, and also in the spring, when water is rough, and Im very shallow, and want to plane quickly. It is also a great prop if you have 3 people in the boat, and/or a shad tank on the rear deck. It is not a speed prop, but it will sure plane a load, and in the winter, or in 3 chop, I dont care much about top end anyway. Mike Whitten/Germantown, TN
