I'm currently running a 25p fury 3 on my Yamaha 200 ox66 and was always happy with it with lead batteries. I previously had a 36v fortrex with 3 group 27's and at start of last summer I switched to a 24v ultrex and 2 100ah Dakotas lithiums. I also had the aluminum deck extension installed. Im looking for prop that will give me more bow lift as I feel with the light back end and heavy bow the fury just isn't giving me the lift I want. Any help is appreciated!
