OK Ron, thank you very much.
So explain me two thing, because my english is not very good.
First, when you say that the carb should be set with a slight lag when i blip the trottle, this is when i hold the boat out of water? And to have this slight lag, you obtain it with a richer HSN, right??
And second, for the prop shaft, the better one is with a straight prop shaft or flexible one??
Thank you
