This is normal for merc's some of the water is used to cool the exhaust . . . Water spray/spit will come out of those ports.
The wimpy water pump action is a result of the poppet valve. When the motor comes up to TEMP the valve opens up (from pressure) and water flows freely out the pee-hole. This is also normal. Some people remove that valve . . . If you do a search on mercury poppet valve and you'll get more info than you ever wanted.
