[Public-List] High Temperature

[crufone at comcast.net]

Jim,
Did you rebuild the water pump yourself? If not check to see if the proper impeller was installed and also installed properly,i.e., to turn the correct direction. If this problem just occurred and was not present prior to rebuilding the pump or replacing the Thermostat I would check those two items first. My normal course for diagnosis is to revisit what was changed most recently. Just because the pump was rebuilt doesn't mean it was done properly or carefully. Brian Zinzer just worked on his pump on #134 so perhaps he can give you some pointers. I don't know, could they have reversed the hoses when they were put back on the pump?

Has anyone else experienced this?

We have a 1965 Alberg 30 with a Graymarine engine.
The Sherwood water pump was recently rebuilt.
The faceplate on the pump, the end opposite the sheave, is hot to the touch.
The water exiting from the exhaust appears to have some steam in it or maybe just hot water.
The thermostat was recently replaced with a new 160 degree thermostat.
The engine block is also hot to the touch.

The engine runs very well and smoothly,  there is lots of water coming out of the exhaust.

Any help would be greatly appreciated.
