Fresh Water pump Gasket - dry or treated

I have to replace the fresh water pump on my Yanmar 3GM30F. I've ordered the pump with a new gasket. I haven't done engine work for sometime and I realized I don't know if the gasket goes on dry or if you treat it with gasket dressing. Anyone know for sure?

A wee smear of gasket dressing would not do any harm.
They are supposed to go on dry, unless the surfaces are marked, but I have heard that before.
