    2008 250 hpdi throttle not working properly......need help!

    I have only been able to get 5300 rpm on my skeeter 20i with a 25-T1 prop worked by Croxton and should be getting close to 6000 rpm's. I have changed all the filters except the VST filter and do not feel I have a fuel issue based on what the other filters look like. I had the boat at the dealer and he hooked the motor up to his computer and determined that the throttle should show from a range of zero to 90 degree's (?) and mine only reaches 72 degree's which is why the motor is not hitting 6000 rpm. The only problem is, the mechanic could not determine how to fix the problem and had to get back to "scheduled boat repairs". We started at the hot foot and then on the motor making several adjustments to no avail. Also, he did a leak down test and motor checked out good and only has 100 hours. Anyone experience the same problem and knows the fix? Thanks

    If you remove the airbox and press the hotfoot do the butterfly valves open fully? You can visually check this without the engine running of course.

    Current: 2006 ~ 20i ~ 250 HPDI ~ T1-25p
    Previous: 2005 ~ ZX 225 ~ 250 HPDI Phase III - TXP 26p

    They open but didn't look to be 90 degrees and the computer shows them only opening at 72 degrees. Mechanic said the computer is not receiving the correct signal based on this issue which is why I can't get over 5300 rpm????
