I found out that 3 blades prop are cheaper than 4 blades, and apparently 3 blades are even more efficient. Don't know if that this is true, but i'm looking at this option.
That being said, i want a second propeller that i will use as a main or spare prop on my supreme v220 with 1.46 geared tranny.
The current prop that came from factory is an acme 537: 13.5X16 L 1.1-18.
What would be a close equivalent to it? I would look also to a slightly lower pitch increase holeshot.
Thanks for the help!
