[Public-list] Gray- Marine

[Brian Zinser]

Tom:

For what its worth, I have 134 with a Gray Marine Engine.  The boat has 
always been wintered above the 45th and it has never had anti freeze 
run through it.  To winterize, I remove the water pump impellor and 
pull the plug from the engine block and the plug on the bottom of the 
manifold. In 40 years there has never been any damage.
