Yes they have lasted longer in testing and they are a little less torquey than their sister 2 strokes. They loose about 1 GPH on fuel burn from our testing, though you are not inserting any oil into an separate reservoir. Their pricing is a fidget more and they require digital throttle on the Verado. That raises the price a fidget also. Otherwise you loose our estimate of about 5 mph on the top and, and about 2 to 3 seconds in hole shot on some set ups. BCB
