the motor is throwing lots of water out of the back of the motor, but the telltail is only dribbling and sometimes stops completely.What's ther problem; how do you fix it; and will t hurt the motor to run it like that?

The impeller is the primary rotating component of the water pump assy.Also remove and inspect or replace your engines thermostat.They get crudded up after a couple of seasons use and don't open and close fully.
