Is this some kind of a kit, or miscellanous parts together?
River Raiders sells a kit similar to this, but it's like $450. I built this for just over $100. I ordered the air box mount from River Raiders for $25 and put the rest together myself. Beamer Pilot.... It is off a tractor, forklift to be exact. Meckanix, I found the top hat by doing a lot of searching myself. Forklift Hood Inlet is the magic google search. Intella Forklift parts is who I got the part from for like $35. It's very well built with a 3" inlet. Pretty sure it's the same one River Raiders uses/sells. The rest I found at a local parts store. A expandable 3" air hose and two 3" throttle bodies to mount the hood inlet. 4 stainless steel bolts to mount it to the cowl and boom, snorkel.
And XJINTX, where I come from, if the water is 6" over your hood, it's probably best to try to find another, shallower route. I tip my hat to others who are that hard core about making water crossing. But water that is that deep, it's not my cup of tea. :coffeedrink:
