Look in a jet ski magazine for the best deals for the sponsons because I am not sure who makes them? With the pitch of the impeller, I honestly cannot remember because it has been many years since I looked at doing that. I believe the more angled the pitch is, the better hook up you get but the straighter or less angled it is, you get better top end. I could be wrong on that though so don't quote me.
