Just curious if anyone has experience with both on an Eyra? I assume both would swing a similar 27” pitch prop having the same LU gear ratio of 1.75 being a TM on the 300 and the extra speed from the 300 would be offset by the extra rpms it can turn based on prop slip calculator. The 300 with it’s bigger cams and shorter intake runners is a little softer on the lowend I thought than the 250ProXS, but probably hard to compare as it also swings a smaller pitch prop given it’s lower rpm limit.
