alarm at 37k + rpm

[Frankp43]

I am getting an alarm at plane speeds and cannot tell if it is water or oil related. There seems to be good water flow thru the tell tale hole and the oil reservoir on engine and holding tank are at full levels. The engine is a 2000 150 HP TRP DX150TLRZ. Thank you for any help

Good news is that you have a 2001 model.

Do you have the digital tachometer? Any indication when the alarm is sounding? Lower left on tach gauge is the temp and if overtemp will have flashing bar above the thermometer symbol. Three circles lower center are the oil status indicators... do you show all three or flashing?
