Fly High Pro X Series Side Sacs (SET) -Wake Ballast
Fat Sac Side Set for Wake Improvement
The Pro X Series Side Sacs fit along the side of the engine compartment on inboard boats and they will conform to fit under the seats of open bow boats. They are designed to get more weight forward in the boat to balance any ballast you may have back by the engine. Their narrow profile also makes for a better fit than a Fat Sac™.
