One other thing I was advised, is not to drain the block. It seems to make
sense as that will expose the block to air (oxygen), with the moisture
present will make things worse.

Of course if you are winterising, that's another matter and some kind of
inhibitor should be used. I don't have this problem, no winters over here.

I'm fairly new to motor boats, we now have a Mercruiser 5.0, operated in
sal****er only. Is there a better way to flush other than the "ears" over
the outdrive? I thought at one time there was some kind of setup to flush
the motor without running it, anyone know for sure?

TIA
