Water crossing depth on northstar

[Ridge69]

I seen our XP Northstar has a max depth of 17" and the non HVAC model is 28" and I assume it's the cover over the Alt. And AC compressor and the duct outlet should stay above water. I have no real interest for go in deep water but crossed a few deeper than thought in past.
Can that exhaust snorkel be raised with a kit? Watched some Vids of dirt dudes with a northstar go to top of hood but I feel he doesn't care.
Thanks for any help
