I have a 2007 25 HP Yamaha that I have a question about. The motor cranks perfect and runs great as long as I dont let it idle very long. At idle speed, the motor is barely trickling/pumping water. After a couple of minutes, the Temperature Warning Horn goes off. If I crank the motor and then throttle it up half way, the motor pumps/pees a steady stream and no warning horn goes off. Do I need to replace the water pump or impeller or is it possible something else? I had someone tell me it could be a sensor, but that doesn’t sound right to me. Also if it is a water pump or impeller, any idea how much to have it repaired? Any info will be greatly appreciated!
2007 yamaha should have a 3 year warranty. Shouldn’t cost you anything if you’re still before the 3 year mark.

sounds like a bad waterpump to me
the faster you rev the motor the faster teh waterpump spins

My luck, the warranty just went out in January of this year. Any idea how much to replace the water pump?
warranty doesnt cover waterpump anyway
its a wear item. like brakes on your car
