i had that issue on my Skeeter, back in those days (2000 model) they didnt bond the hulls. Not sure if they do now or not. My boat was 6 months old and I was able to lift the top cap about 6″ off the bottom cap, broke all the screws which I didnt know needed to be tightened almost monthly. WHAT A PAIN!!!!!! And you could feel the “looseness” in the ride, the whole boat would flex in rough water, it was aweful. One of the reasons I made the switch to a Cat…..now there is no turning back!
