Hi guys, I get an annoying helm alarm beeping floating up from somewhere under the instrument panel every time I go over around 10 knots. It does not stop until I slow down and then stops completely. No overheating according to gauges. Oil just topped up. No change in speed and no special vibration. Water is deep so no depth finder issue. I thought it was the vhf which had a warning notice but I resolved that issue and beeping still continues. It continues also even if I shut radio completely off. Extremely annoying. Any thoughts? It is definitely a beeping not a steady noise type alarm.
