I’ve got an ‘88 55SS that I “upgraded” to a Garmin Reactor autopilot last year. I’ve had nothing but trouble with it. Following a heading it does okay, until any wake hits and it over counters, causing more roll which it counters again, continuously increasing the roll. The auto tuning was terrible, e had to manually override every setting, and the auto tune wasn’t close. During troubleshooting. Garmin replaced all the hardware so I don’t think that’s the issue. It does seem to follow a course a bit better, but Garmin doesn’t allow me to reset XTE, so when I have to deviate from the course and deactivate the pilot it turns sharply to re-establish the original line, instead of being able to set a new line from current position. Last week, the rudder indicator went crazy, showing hard to prot no matter what I did. After disconnecting and repowering everyhting, the indicator started working. Now the pilot will run for about 5 seconds before turning the rudder hard over (different directions each time). Garmin support wasn’t really able to help much at all, and I’ve spend dozens of hour troubleshooting various issue with Garmin and my installer. I’m looking at replacing the pilot with a Raymarine Evolution pilot, and likely replace all the remaining Garmin equipment. I’m in Ontario, Canada and there seem to be no super Garmin installers around that may have some answers we haven’t seen. I find it hard to believe that the Garmin pilot is as bad as my experience shows. Maybe it simple can’t handle my boat? Maybe my boat is too unstable for any autopilot (which I doubt). Any comments would be welcome before I spend a ton of money redoing my electronics.
