Assuming your batteries are charged as we have learned, the electronics on these boats don’t do well with low voltage!
As an update, the gate and positions on the LSE’s are very finicky. The BCU errors after shutting the engines down are typically caused by:
- Gate adjustment for full open/closed
- Cable friction or binding
- debri stuck in the gate
It took some time and help, but was able to reproduce, duplicate and prevent BCU errors for the remainder of last season. The BCU errors commonly occurred by:
- turning the wheel 90%+ to either the left or the right and shutting the engines down.
- shutting engines down in Single Throttle mode resulted in the most consistent BCU error with the wheel turned
This winter, the boat spent some time at the dealer with a very specific description of how to duplicate the error. After confirming, they had Yamaha instruct them to adjust the cables in increments and test until the errors went away. There may have been a software update as well.
Hope this helps. Don’t let the BCU errors from enjoying the boat. We used ours for many times last year avoiding the BCU errors by not shutting the engines down in single lever mode and straightening the wheel before the engines were shut down. Since the dealer did adjustments, we haven’t put a lot of hours on it, but in my limited testing since those adjustments, we haven’t been able to reproduce the BCU errors. Hopefully this indicates the issue has been resolved.
If you get the error on the water, make sure the wheel is straight, turn the batteries and key off for a few minutes and then try a few restarts of the motor. Once this was done, mine usually cleared and everything was back to normal.
In playing around with the gates, I also found placing the gates in manual override operation and resetting them to full open (with the batteries and key off) then re-engaging them and turning the batteries back on would clear it. That’s a pain in the butt, so most of the time it was a battery/start combination, but usually managed to get it to reset fairly quickly every time once I got the combination down.
Don’t get me wrong, the boat should never have had the issue, but learning the cause enabled preventative measures that produced many BCU error free outings and allowed us to use the boat for the rest of the season without frustration. It will be interesting to see if the issue is really resolved or not. I’ll keep you posted.
