77' 23' Ctr Console Poter Built - water coming up through scuppers/drain holes

[Mudhen]

Just put the boat in today and took her for a spin and noticed that I had a decent amount of water bubbling up through the drain holes/scuppers on the deck in the transom of the boat. Only happened above 26-28mph, once I slowed down it would drain out . . . .I have had the boat for 10 years and have never had that much water come in. Happened heading into the current and away.

Anybody have this problem or have any idea what could be causing it ?

Thanks
