Hey guys, I am trying to find out what my choices might be for my 0-200 in my j-3. The stc lists mccauley 1a101 6944. I have a 1b90 7044 but it Has to be 71 inch minimum. The prop shop I talked to said this 6944 would be a loss of performance and something like a 7440 would be great but I dont understand the approval process.Any advice will be welcomed.
