Audible alarm Mercruiser 5.0 carb TKS B2

[PB5117]

Hi there,

Looking in this great forum unfortunately i didn't find the solution for my problem:

I have a twin engine boat (2007, first owner) with a merc 5.0 TKS carburator, raw water pick-up (fresh water) and a bravo 2 drive with standard prop.
i often have a audible alarm on the sb machine if i drive more than 2500RPM.
sometimes it's just a very short beep, sometimes it takes seconds and doesn't stop till i stop the engine.
gear lube level is full, temperature is allways bewteen 170 and 175, oil pressure on low power 40psi, mid power 60psi an at wot 65/70psi.
Also, the motor runs fine, no strange sounds and the performance is okay.

i disconnected the blue/tan cable of the gear lube sensor, still alarm
also with the oil pressure sensor, still alarm
unfortunately i can not find the sensor of the thermostat, there only is a brown cable which goes to the temp indicator.

however, can i resume the problem is in the temp sensor? or what else can be the problem in the ccoling system?

hope you can help me
