I have a 2000 promaster with a 1999 120 force motor, the problem that I have is last year I change my water pump. Every thing was working find 8 months later my over heat buzzer was going off when I travel around 30 knots I slow down and come to a complete stop and water is coming out on my tell-tale after a minute its goes off. Well I decide to change my thermostat since it was the orginal that came with the boat. I change my thermostat and seal with new gasket started the motor to see if everything was already but now water that comes out of the tell-tale is barly coming out but after a minute a steady flow of water comes out an then it stop to bearly coming out. So what problem do I have.
