View Full Version : Sterndrive disengaging when trimming

"I have a 1994 Dyasty Cabin Cruiser with a 454 chevy block and a Yamaha sterndrive. The problem is when I am crusing and plained out I go to adjust the trim on the drive for optimal plain. Well as soon as I hit the trim button on the throttle stick the drive is coming out of gear and the engine revs. But then as soon as I let off the trim it pops back into gear and continues on fine. Also I noticed that the radio clicks when I trim also. I cant find much information on this drive seeing that they only produced them a couple years. I was thinking maybe I have a lose wire or bad ground creating a short circiut? I was wondering what you think and what would be the best way to start trouble shooting. Also these drive's clutches are vicous cupling system, could this also contribute? Thank you!"

Check and clean all grounds in the system.
