Hummingbird buzzer

[gajud]

Hey guys, I have a question! Today I was running down the lake pretty hard when an alarm went off on my humming bird 798. It sounded just like when a water pump goes out. Thinking that is what it must be I shut it down, check the motor, it’s cool, a strong stream of water from the pump. Now I am thinking that we are not pumping enough water when the boat is on plane. So I have my partner position himself so he can watch once we are back on plane, we are still pumping strong and I can’t get it to repeat this sound.
I am sure now that the sound came from the HB unit. We were in 28 ft of water and I have no shallow water alarms turned on that I am aware of. Any ideas?

Numerous alarms on the 798....had a low voltage alarm that would go off at the strangest times. I just shut it off all together.
