Tilt/Trim Alarm on 115 Yamaha
 

I have a '96 115 yamaha that is having an issue when I am at crusing
speed and I try to trim the engine either up or down, the alarm under
the console goes off. As soon as I bring the engine back down to
idle, the alarm then shuts off. I never have this issue at any other
time other than when I am on plane. This doesn't happen everytime,
just enough to be annoying. Any suggestions?
