Anybody have any real world experience with these boxes?

Interesting, I have never seen these before either. What's the $$ I wonder?

Dave M

Probably too much! When you click on pricing, it asks for your contact info. WTF?

DAve go to the cig section and look at ktrons blackhawk vid, he has one , he also machined it and took some of the weight out of it. I have an ITS on my 20 and if I need to go back more I will get one as well.

Dave M

Thanks! That's a pretty nice setup. Just the fact that I have ITS is somewhat out of the ordinary for a Y2K. I know of another with ITS, and one with a Konrad. So, there's not a lot of R&D with boxes. My numbers seem to be in line with other Y2K's without any setback. I don't know if more setback would benefit me or not.

That is interesting. I have an ITS as well. I guess you need a custom input shaft to run that?

the main thing to consider for set back is each foot back, your prop goes down an inch, so with the 7 inch ITS box, your prop shaft is approx 5/8 inch lower. if your testing how your boat reacts to diff depths, check with spacers, for me the boats i have ridden in with boxes whether ITS or imco needed them further back to keep a little more of the back of the boat in the water and to help with re entry, they also planed better as more prop was in the water. imco also has a box that can raise x dim.

I think it comes with the kit.
