2 beeps per minute

[chambers1517]

I have a Mercruiser 350 MPI. WhenIi first start the boat it runs great but once warm I get a 2 beep per minute alarm. I checked the temp sender and it never changed. What else would be triggered after the boat is warmed up?

Check the drive oil reservoir, And while you are at it, engine oil, and give it a good look over. On newer ones some have a water pressure sensor also. Have you changed the impeller lately?

Serial number please????????????????????

Several things can cause the 2 beeps per minute, the main cause is the sea water pressure sensor

Thanks guys for the feed back. I thought about the water pressure. My drive is a Bravo one and it has 4 water holes on the front of the drive that should pressurize while underway. Would the engine being warm have any impact on water pressure. I also tried to eliminate the drive lube by filling the reservoir. The oil pressure runs at a steady 40psi while underway but the alarm continues.

Oil pressure will not do a 2 beep, there are many others that will
