I am running a rotator 2.68 with a 80.5” R 3 blade and right now with a completely stock junk yard pull out it’s pitched to turn 6k which I plan on adding pitch before next outing and cruise is around 3600-4000 but gets almost identical fuel consumption as my Buick boat did. I have only run 25 gallons through the bot so far and ran with a buddy that has a panther with a 5.7ls and I never get over 140* weather I am running it dry or on the lake. Mind you I have a true 7’ running bottom. With the new engine build I am hoping for as close to mr whine’s idea of the perfect combo
