hey, i have a question about my 2002 mercury 15m 2 stroke. while running the other day i was looking back at my motor and noticed the two holes, on either side of the outboard just above the lower unit, were putting water out. the holes open the area where the water pump, shift rod and main shaft are to the outside. the tell tale is putting out a good steady stream of water. was wondering if this maybe water pump blowby. the water pump is connected to the pipe up to the power head by a rubber piece (nothing clamping it)so it probably can't be totally water tight. is it normal to have some water coming out of these holes? where does cooling water go after it has gone up into the powerhead? out with the exhaust? thanks in advance.
