115 0pti water pressure alarm

[BCRick]

I have a 2006 115 opti with 920 hours on it and it has been serviced every 100 hours since new. Never a hiccup til now. I have the smart tach and the water pressure alarm has started sounding and the pressure is fluctuating between .39 bars to 1.15 bars and the alarm sounds when it drops to the lower range then stops as it comes back up. What is the normal pressure and will it hurt it to keep running? It is a Sunday and I can't get any response from my dealer. Anyone have any ideas?

Re: 115 0pti water pressure alarm

I just got a call back from my mechanic and he figures it is the sensor that is the problem. I'll get it replaced tomorrow and be back in business. There was no cooling issue so hopefully it stays a great reliable motor. I run it as a patrol boat with about 300+ hours per year so far so good. Hopes this might give someone else a clue. I'll post back if it turns out to be anything else.
