Norm, what diameter and how many blades are you running .. and did you have something else beforehand with some comparison numbers?

I will soon have a medium 3 blade IFA available for sale.
I am awaiting arrival of an airmaster cs with whirlwind blades.
I also have a 2 blade ground adjustable Sensenich EZ-pitch 70" with nickel leading edges for the 912.
Private message me for more info.

I am running a three blade IVO with IFA and cruise about 105mph fast cruise. Before I put the IFA into service I was running it with ground adjustable and cruise was about 90 to 95mph on the 80hp 912. I had run a two blade warp drive on another plane with a 582 and found the Warp to be a big heavy club that shook far too much. I know some people have used the three blade and it is much smoother. Kevin just replied that he may have a IVO medium with IFA so that may be a great option for you. He is in SK so easy shipping.
Keep in mind the early 912 had the same bolt pattern as the 503 and 582 gearbox but later 912s changed the bolt pattern. Make sure what you get is what you need.

this 80hp has a 4 inch prop bolt circle, unless they call it 3 15/16 or 99mm
regards
Rotax bolt patterns are 75 MM, 100 MM, and it seems that latest size on new 912s is 101.6 MM. JImChuk
