Running on water - exhaust manifold gaskets query

[kevin de witte]

1999 Merc 15 hp. Are these gaskets designed to leak water from the water cooling chambers into the exhaust manifold and how much?? If it is too much (faulty gasket)could water be returned to the carby via the crankcase breathers and cause power loss at WOT?
