had this thing a little over a year now and added a crossover during duck season, absolutely love the thing and im pretty happy with how it performs.
Empty it will go steady 27 and bump 28 in perfect water conditions
but last night out bowfising really suprised me, with four people, a generator, lights, a full ice chest with glass bottles inside, all of our bows and other miscelaneos boat stuff and a raised floor it had a little over 1000 pounds in it and was going a steady 23 and bumping 24 in deep water, leavng the ramp i thought there was no way it would get on plane and just plow all the way like it did the summer before with the same load, i dont think this had anything to do with the exhaust but increased tiller time, but as i said im very pleased with how my stock engine is runnin on a non mud hull
