The new flags are like 3 bucks each. Not even worth drilling the old. The other models is taking the screw eye from the front and relocating it to the rear much lower and moving the rattle flag tow arm through the new eye.

This stops pulling the board down in back from the top corner allowing the front angled section back into the water..........

But if you try to run cranks this way the board pull so far up that when you turn they fall over very easy.

I have pics I can send but they are not adding here
