I have the Furuno Navpilot 300 linked to a 2019 TZTouch 2 on my Carolina Classic 28. Several months ago, while the autopilot was engaged, the rudders went full over full port. Shortly thereafter after the error message “rudder deviation alert” followed by “check drive motor change circuit “.
I conducted Honour Marine who did my electronics installation and they came down and did the dockside tests which all checked out for fine. We took the boat out and tested it and everything worked perfectly until a couple of trips later when it failed again with the same error message.
We sent the processor into Furuno who benched tested it and could find nothing wrong.
We reinstalled it, did the various setups/check’s which it all passed only to have it fail midway through our next trip. Again same symptoms/error messages.
Then again working with Honour Marine we replaced sequentially the following components:
1. Processor
2. Control Unit
3. Hydraulic Pump
After each we went through the dockside setups and checks (which it passed) only to have it fail one or two trips later each time again with the same symptoms/error messages.
Prior to our most recent trip, we went into the Parameters and changed from Self Learning to Manual. From there, we adjusted the various settings to broader tolerances hoping that we could minimize the amount of “work” the autopilot was doing. Again roughly midway to two thirds it failed the same way.
Thoughts/Suggestions? My arm, never mind my crews, are going to fall off….
