Jrod,imagine the heater core bustin so bad that it's equivalent to just taking the hose off and even more....That is how bad one of my heater cores was and my amp rack was not hooked up that way at the time(they were lower)and no problems,other then I almost sunk my baby right at disco bay in the no wake zone.
Ohh and Jrod....approx 50 gallons of water would flood the boat in a second which is pretty equivalent of a good wake over the bow....not that I get my boat wet but it's not like the sack is going to pop every time out either or at all.
There is absolutely nothing under the bow seats that would even get close of poping the sack other then sharp fiberglass from the deck plus everything is carpeted in there as well.
not really worried about the sack busting or not,either way my boat will be ok and will dry out.
