I have a 2004 Yamaha 60 HP 2-stroke. Buzzer would sound (continuous not beeps) 10-15 into the trip. Guessed the water pump and thermostat needed changed so I changed both and I'm still getting the buzzer after 10 min or so. Water is coming out of the port just fine but is cold, not warm. Disconnected pink wire going into cylinder head and buzzer is still going off. 2-stroke oil is being used. Once I shut it off and the place the key to "on" (eng not running) buzzer is still on.

Any ideas?

Check the main wire harness gang plug on the engine side, the terminals should be clean of anything.
