I just got back from doing test runs today. I am getting the props done by Bronson Hill and wanted to send him numbers so he could use them in his adjustments.

I have the same engine as HTM SS 24 and compared to their numbers it seems unbelievable given that a cat is supposed to be faster. The speed at rpm is about the same, but acceleration in my batboat is awesome. I want to go 100+, but what will that do to the acceleration?
