In deep fluffy powder all three of these machines run water temps in the 125-130 degree F range. We ran the machines down a packed powder trail, very typical of what one sees in Western riding areas when going to or coming from backcountry riding areas, for 5 miles with the scratchers snapped up out of the snow. We watched the water temps on the Avenger gauges closely. After just 2 miles the Genesis Cat was above the 165 degree F threshold we had established as our upper limit and we had to pull over and cool it down. They held this temp pretty consist over the five mile stretch, making us nervous about exceeding 165 F, but never causing us to stop and cool them off.
Snow is thrown off the scratcher onto the track, slide rail, and tunnel.
We then deployed the scratchers and ran the 5 mile stretch of trail again. The results really were amazing. We even tried riding harder, slower, drag raced the sleds, and even purposely sought out the spots on the trail with the least amount of snow. Nothing could cause the temps to climb above that 135-142 F temp range. Those are indeed impressive results.
