    Skid plate changes..

    I had no idea there were so many different plates for the 21 ftrs. Especially on some of the Prosport's !!! I'm sure it's been a work in progress. Mine sticks out 4.1/2" is 19.1/8" wide-- it's straight across at the back with the outer edges turned down. It can be a handful to drive at higher speeds. Now I'm wondering how much of that can be from my plate ?? Would like to know what the dimensions are of the one shown in Allison's webpage. It appears in the picture that the trailing edge is far from being straight across like mine.

    There seems to be a general consensus that the longer one is better for those who struggle with hole shot due to load and or elevation.
    But there is some tradeoff in high speed handling and traversing BIG waves. I'm one who struggles with hole shot and has to run big open water. Some recent threads have me curious to find what works best for others especially with the handling and rough water. My rig is also prone to porpoise at slow speeds (some props) are worse than others.
    I tried the Allison cavitation plate foil on my last Allison but did not like the way it caused the boat to act in big waves.. It does what it's designed to do (pushes the nose down) !! On a 2003 in big waves that will get you wet !!!

    Would be real nice to know ALL the particulars of D.S. setup in those Columbia river videos ??

    What's the deal with the bend down the sides?

    I want one like River Rockets >>>
    Curious to hear the story behind his.. sure seems to work very well ..looks like it would take some major mold changes to do that.

    I cut mine even with the back of the hull then added a jackplate bottoms plate. I get more bow rise but it isn’t an issue. Even Geoff’s 32 BC 4 came out well.

    Doing it again... I would probably try only cutting 2” off first. Given that is essentially how the new ones are

    That's whast I'm going to do. Just wonder what's the deal with the Darth Vader Tie Fighter bend on the sides..

    I cut 4 inches off mine I think, left 1/2 inch sticking out beyond the transom. Very little effect on the hole shot but really made it feel more sure footed in rough water and at faster speeds.

    How much faster is a red one? Where did you get it powder coated?

    Same speed, buddy and I did the powder coating. It turned out ok. The 1 question I don't get anymore "what the heck is that?" It just blends in now.
