Ok, having read all there is to read about prop selection, I have finally come to the conclusion that the enertia prop is going to be the best for my application. My boat is an SD 217 Hurricane deck boat with a 5.0L MPI 2005 Alpha drive. The mercruiser prop selector suggests the Enertia 20P model number 48-899000A46. I currently run a Vengeance 19P. Ok the Enertia must be made of gold cause it really drains the wallet. I found the same model number on an Ebay store but they say it comes with a Flo-Torq II hub kit and is also 14.25 inches in diameter when the Mercury prop selector says its supposed to be 13.8 inches. Sounds like the wrong prop but the model is exactly the same. I emailed the Ebay store but so far no response. Is this the prop I need or what? If not where can I find it at somewhat of a reasonable price? Does enertia use the same exact model number prop for different applications? I am terribly confused.
