I consistently get a single long beep from my 2011 twin 350 mags. I have isolated the beep to the following condition:
port engine in reverse (at roughly idle speed)
straboard engine forward (at roughly idle speed)
It happens every time I dock. I have checked fluid levels, pressure, temps etc...
This season is the first it has happened. I was actually thinking it could be my depth finder?? Is it possible the this combination of engine direction is causing a disturbance in the water that would signal low depth??? Just a thought. I can test this weekend by turning off the depth finder.
Any other thoughts or advise would be appreciated!
