    That just doesn't seem right. My 250 4s will turn a 24p fury to 6200 at 75 loaded and 80+ water temps. I was actually thinking of getting a 25 or 26 at some point.

    how many hours are on your motor? is it broke in...… how high are you running the motor?

    there is a 921 phx with 12 bobs hydro and 300r motor that is broke in and running high on jack plate with 27 fury 3 blade or 26...… no back seat no front seat and passenger side console removed and 3/4 tank of fuel running 81 and change and bumping 82 some...no pwr poles not sure of battery's agm or lithium... I have no knowledge of the difference between 300r and 300 pro xs…. but I would agree with you some thing is off....

    Kry29 you are very close to Beaumont so I believe you know...…I am unsure if he would want his name on the internet....but you and I both know the boat and motor came from Jordan Marine....
