Trim alarm

[Herbieville]

The port drive's trim alarm seems to keep coming on every couple of minutes or so while cruising. I think it is the trim alarm because the audible alarm beeps and then the port engine digital display shows the trim setting momentarily. The setting itself seems to drift from 0 to 1. The analog trim setting moves as well. Any ideas?

Thanks!

Gear oil?

Had more of the same on the trip home. Alarming every couple of minutes and trim was stable. Idling was not steady so I suspected IAC issues. Searching around here after return makes me think it is the IAC on the starboard engine. Ordered a replacement. If turns out to fix the problem, I will order another spare as these things seem to fail quite often and that beeping is annoying!
