Floor 20 cc 1978

[Fatfish]

Hey guys new to forum just purchased a 1978 20 cc and the transom has been closed in my plan is an Armstrong bracket with flotation and a 140 Suzuki . We are redoing the floor first and someone told me I needed to raise the floor so th scuppers would work . Any info would be great . Also I have a completely redone center consul I will be selling I'm opting to go with a smaller cc
