Serial # 2B571507. 2019 250 Pro XS. Dropped my boat off at a Merc dealer to see if Hotfoot was opening throttle all the way. They called to say sensor was showing that it was opening 91%. They called Merc to double check to see if that was in spec and haven't heard back. Don or anyone have any idea on this? The dealer seems to believe that 90 tp 100% is with in spec. I just cant get this motor to turn over 5800 rpm. I have been running a 24 4 blade Fury but tried a 23 3 blade Fury off a friends boat and got the same 5800 rpm. My 24 hole shots just fine even with a load and no matter where I run on my Atlas and how I trim it, it seems like its stuck at 5800??
