Its been doing a constant beep randomly for a while now but lately its almost every trip. We just replaced the impeller and its still doing it. The thing is it will only do it about 1 minute into first start time. I can remain at idle or even full throttle and it will beep at the exact same time so I know its not an over-rev. Once I let it sit for about 30 seconds I start the motor up and can go all day and it will never happen again. Yesterday it didn't beep at all at first but then the motor wasn't turned on for over 2 hours and then the constant beep came on and it went into guardian mode. Ive been thinking about changing the temp and oil sensor but want some feedback before I spend the money. Thank you!
