Isnt it the FTRA knock off? If so, then it does NOT have water issues.. I proved it this last weekend. I went through water that was just shy of the bottom of my windows. I DID pull the rubber seal that seals the normal opening though. Water is heavier than air so itll pull air from the stock opening before it pulls water up (defeating gravity) the bottom opening. Also, I have had NO overheating issues that some claim.
