I am going to be winterizing my boat this Saturday following Cabs directions. I have a 2007 LS (direct drive). I cannot find that muffler plug that Cab says to drain anywhere! So three questions. One, is there a muffler plug on the LS? Two, If there is, where the heck is it? Three, If there is and I can't find it and don't drain it, how serious is that?

Thank you,

Garn
