This is no lie, my wife, I love her, has always been a little mathematically challenged. One day us and another couple who own a towboat too were chatting about how expensive these boats are filling up, how we would fill up for 150 something dollars, blah, blah,blah. Well wifey goes on her iphone and starts her calculation on how many hours and how many gallons we use, and so on, she's pecking away at her phone and then lifts her head and goes, "we use 18400$ of gas on a weekend?" We all busted out laughing and have not let her forget it since. Well, based on her calculations, if this new 5000$ prop can save 9-15% in gas, it might be worth buying it right now!

Can someone explain how cup works? I know what it is. Lets say you have the exact same prop, but 1 has .075 cup, and the other has .150 cup. What are the results?

The way it was explained to me by someone at ACME was that cup mimics diameter and helps with overall efficiency. I was also told that about 0.050 of increased cup will affect your RPM the same way that increasing 1" of pitch will. I'm no expert, but I understand all this to mean that for props that are otherwise identical, the one with more cup is going to surf at a lower RPM and have a higher top speed.

Still loving this ACME 16x13.9 prop on a 400/1.76.
Great prop.
