I was fighting the motor. When we boat at 6,000 ft with the 400 it struggles with our 5,600 lbs of ballast and a few folks in the boat. I had to prop down for it. I put a 15.5x14.25 on it and had enough power but then I was surfing at 4300-4400 RPMs. At that rpm I was burning fuel like crazy. I think I was burning between 10-12 GPH. The noise was pretty unbearable as well. I put a surf pipe and put kilmat all over the floor but when you are revved that high you can only do so much. Otherwise loved my Max.
