I overheated on my first trip out. I replaced the impeller which was a mess and restarted the engine but the water is not circulating. The Temp guage goes to 250 as soon as I turn key to on even without turning over motor and goes to 0 when off. I have forced water through the hoses and it comes out the water discharge holes and the intake. The belt is turning the water pump pulley. Any suggestions?
