[Public-List] 2nd attempt ... Winterizing a GrayMarine SeaScout engine

[Brian Zinser]

Michael and Hugh:

I live above the 45th and all I do is remove the two plugs (the third 
plug the manual is referring to is on the bottom of the water pump which 
I don't remove.  Instead, I take the plate and gasket off the pump and 
remove the impeller.  Mike is right about the locations of the plugs.  
The one on the bottom of the muffler is very hard to find and put back 
in.  I have the hole marked because you have to do that one entirely by 
feel.

Anyway, my system has never had anti-freeze put in and it gets down to 
-40 (F and C are the same at this point) up here.  40 plus years and no 
problems.
