I am trying to winterize the boat and I have only found 3 blue drain plugs so far. One on the front of the engine lower left side and one under each manifold. I'm sure there are probably more but can't find any. If anyone knows the number of plugs and location for this engine I would appreciate if you let me know. 2009 4.3l TKS in Bayliner 185
Thank you
