Believe my live well switch below the throttle lever is broken as cannot control in/out of live well. Do not fish tournaments any more and do not need water coming in with the extra weight in the rear. The drivers side has 1 screen (drain) right near bottom close to divider, the passenger side has 1 the same also close to divider - the passenger side also has screen/hole just above the other screen. Assume the 2 on the bottom are gravity drains and the top on passenger side is to fill with? Does anyone know what size these holes are as would like to block water from being able to come in at all. Local hardware stores may have plugs or maybe can find "cork" the right size but need those hole sizes and where they are located very difficult for me to get an accurate measurement. Thanks
