    I dont think a Fury 3 will work as well as a tempest on that boat. I also believe that many would be happier with a four blade on that boat. If your numbers are accurate that is upward of 20% prop slip. Indicating a serious proplem with the prop or a issue with the running pad.
    How was RPM read, analog or smartcraft. Was speed read on GPS and was it verified by another GPS as well. I found out first hand that a GPS can be wrong. I had a Lowrance unit that was off by 10 MPH. I performed a master reset on the unit and that corrected it.

    It's an analogue gauge which has been verified with laptop and gps was checked in the past. Was within .5mph of the other. Haven't checked it since tho. Was actually using my gps to check the other one haha.

    If the bow isn't rising as it should tho would that not increase slip? If the bow rises more the prop may bit better.

    For sure, I would try to borrow a known good prop preferably a four blade for now and see what the results are. Also take a long straight edge to the bottom of the pad and check for rockers an hooks.
    I recently helped a guy with a Ranger that had a very similar issue and his problem was he had mounted a skimmer transducer on the back of the pad almost directly in front of the lower unit. It disturbed the water flow enough he had almost the same issue has you describe including low water pressure at 3.5 P to P
    Look for any damage on the pad that may disturb that smooth flow to the prop.
    The trim extenders are a cheap diagnostic tool as well, as mentioned above.

    Going to chime in real fast. Now I could be completely wrong here but looking at that picture, there is no way that motor is trimmed all the way down, if that is what you are trying to display. It should be tucked in, if it were trimmed all the way in. Looks like it is still trimmed out as if you were going down the lake. Now I am using the memory of all the motors I have looked at when trimmed down.

    Prop is 90% of your performance.
    Until itís right nothing else will be right.
    Props are weird Iíve taken five new in box props and gotten five different results.
    Why master prop guys are so busy.
    That tempest is the correct wheel but it might need a living touch.

    Iíd try to find a known good one and see what happens. If you get an improvement then get yours worked. If

    I understand what you are saying about the prop, look at the picture, that motor does not appear to be trimmed all the way down for blasting off. So if that very first thing is not correct how can anything else be. Understand what I am trying to say?

    Motor is shown as trimmed WOT. Im trying to find another prop locally but its hard up here. Not a ton of boats that run a 25p prop. I tried the furry and no go. Tempest is better.

    What gets me is the only thing that has changed is the weight out of the back. I seen 74.6 on gps with the fury, mind you the boat had little fuel in it etc. I went to the tempest as the fury sucked with a tournament load.

    I was a diehard tempest guy until I had Ronnie Gilbert rework a Fury for my Cat, for my rig he increased the rake and totally changed the Cupping profile, His prop outperforms any reworked tempest I have used..Much better hole shot and requires less trim than the tempest, will also run a little higher than a stock Fury. Still more weight sensitive than a tempest but overall far superior

    That said though I am not familiar with Nitros, but based on the weight difference and pad design I tend to think a Fury 4 or Trophy may be better for your boat

    Cal him and talk to him about your rig, he is a great guy and will not BS you...……………...337 380 1437
    Ronnie Gilbert is well known for his high performance experience and being a Fury Guru
