Re: Prop Charts
I "think" the data you are looking for is only available on paper from 2 places, in general...Dhadley and/or myself have quite a bit of comparison data on most props.... and the manufacturers have it, but will likely tell you only what they want you to hear. There are also many other independants that have good info, but for a basic guide, it's old-school and just not very close in most cases.
The "basic old rules" used to be 200rpm per inch, 100rpm drop going to SS, and 100-150 drop for each additional blade.
Things have changed dramatically in the prop business and these rules really only remain close if dealing with the exact same model of prop in a different pitch. Each design performs differently on every boat we run them on, and because of that alone, you can't say that a Turbo1 is "X" faster than a stiletto...it has higher efficiency, but the numbers change with each different hull type, which is true of ANY prop that you may run.
I've tried for 3 years to put something together as a guide, but it always ends up being a "this prop runs this-except on this application" type deal.
