I am new here so I hope that I am doing this right. I have a Yamaha T60TLR and after about 4 min. at an idle the heat buzzer goes off and the engine is getting hot. I can see like steam at the motor. Don't have a big stream of water coming out. Well we have changed the pump checked the hose for blockage but still seams to not be getting enough water flow. I could use some advice. Thanks
