Prop Diameter

[Scott1]

I am away from home now and I don't have all the information I need to order a prop.  I want to go one size (pitch) up.  My prop now is an Enertia 17P.  My wife sent me the numbers off the prop and they are

48-898994 17P

When I go to Ebay for the 18P Enertia, they have size 14 1/4", where if you look up the 17P prop it is 14 5/8"   I guess I am lost to know what size fits my boat.

Anyone know?

With the Enertia props, as the pitch goes up, the diameter goes down. I have a 15 x 15.

Yes, I am starting to see this in my research, accept for the Enertia Eco, the diam is 16.  Thanks for the help
