I removed the batteries for 4 days to charge them up.
I went to use to boat and the e shift fly by wire won't select forward or reverse and the orange fault light comes on when the lever is moved to the forward or reverse positions. The engines starts and will only idle. The trim switch works . The blue light is solid all the time. Check engine symbol comes up on yamaha dashboard screen. Has the ethrottle lost its pairing memory to the engine?
