2001 Prostar 209 Predator 310 HP. This is my first winterization on the boat since I bought it this summer. I did not run RV antifreeze, I just drained the block. Looking into the flapper valves on the transom, I noticed there is a low point in the mufflers where water has remained. Do I need to find a way to drain the mufflers? Thanks!

209V? If so they should have drain plugs. If you have one muffler per side, you could separate the exhaust hose from the manifolds and pour some RV anti-freeze in, to lower the freezing temperature.
