New ECO Prop Test

[alldodge]

In the new Boat Test email this month they have Mercury's new ECO prop. Prop has a larger diameter, more progressive rake and is said to be more efficient. In reading through the article they have it compared with their Rev 4 prop. In the article there was no mention of WOT RPM's of both. Also I would like to see what the prop would do when compared to a 3-blade prop of equal WOT RPM.
