Hi I have a 2004 yamaha 150 2 stroke that temp alarm goes on even when I first turn key to on position . after starting the alarm will stay on for 60 seconds It has also gone on a few times once trolling at 1200 rpm and a couple times @3200/3500 rpm if I turn battery switch to off then back to on the alarm goes away. Has had thermostats water pump and temp sensor replaced. Any Ideas ??? THANKS
