You obviously have the urethane roller on the bow. The 2006 models are now black rubber again for this reason.
There is little cushion in the urethane rollers, and if you impact them hard, they cause the bow eye to force the gelcoat from the Vinyl Ester resin behind it.
For those times you run it up a little too fast, you need a little more cushion to prevent this.
You can easily have it repaired.
