I'm wondering if the CLE unit has had a cone job done to it. It has 3 water pick up holes in the cone and the whole bullet tip to end appears to be about 171/2" long, has swept skeg and torque tab, it has some signs of grinding or sanding but overall pretty smooth,its blended in well if it has been done. What cone manufactuer has 3 holes in bottom of cone they look factory done?
