I dont see where the vents would hurt, if anything would only benefit by allowing heat to escape the live well.If you dont have an issue drilling holes in the lids, I only see benefits to the system.I will say having owned a 98 Jag, 2011 Sabre FTD, 2014 Eyra, and a 2016 PII, I have never lost a fish due to excess heat in the live well. I have fished many Tx with the water temp hitting 98 degrees.I have occasionally added a bit of ice. Always helps.
