cooling water trouble 1998 125hp

[salted nuts]

I have been getting a high temp alarm after cruising for a while. I just replaced a broken reed valve #2 cyl. I opened the head cover - no obvious problem, same with exhaust cover/gaskets.I also pulled the thermostat and poppet valve - all in good working order. I get very little pressure and air/gas in pee hole stream. There is a lot of warm water running out of the front of the foot. I replaced the water pump impeller and pump/tube seal. After pressurizing with a garden hose, foot off, I can see water running out from the drive shaft hole. Where could this water be comming from and why do I not have any pressure.

Has someone done some work to the waterpump in the past?<br /><br />If so its possible that they did not silicone the baffle plate that separates the exhaust passage from the waterpump.<br /><br />TMD

I did the service on the water pump and I did silicone the divider plate
