23' CC Scupper Question

[LadyLuck]

wondering how the experts on here would handle this scenario. existing scuppers on a 23' CC are in good condition and blocking in front of scuppers on the bottom of the boat are still in place... my question is with the addition of a hermco bracket and a 300 etec, will these scuppers need to be abandoned and new ones created? i would appreciate any suggestions or experiences from others...thanks
