Well we do get to jump behind zero off boats at Stillwater Lakes in Palm Bay, Florida, but I'm trying to get our boat set-up so he can train more. I am going to try to change out engines for Zero off, but was wondering if the z-box is an option, but I don't think it is. I was also wondering if I need to try to get the 6 liter over the 5.7. Really appreciate your input.
