I understand it puts a little more weight on the box, but 1 or 2 hp and thats all it would be, makes no difference. It's more for towing a small bike trailer and I dont want to get bogged down out in the middle of no-where. And if I do hit my 2nd wind and 3rd childhood, I still have my old motor from 25yrs ago (way before everyone stuffed turbo's in everything) that use to eat xu1's in a datto 1000 in the back of the shed.(probably seized.. Ha)
