Welcome to the Raymarine Forum ray18,

Insufficient power statements such as you have reported may result from insufficient voltage and/or current being supplied to the MFD. Which version of software (HOME->SET-UP->NETWORK->DIAGNOSTICS->PRODUCT INFO) is presently installed with the MFD? Has a 1kW transducer or 600W 50kHz/200kHz additionally been interfaced to the MFD? Were the power leads of the MFD extended? If so, what gauge wire was used to extend its power leads and how much length was added. Were you trolling at the time that the problem was reported? If so, how long had you been trolling? If after returning to dock, connecting the vessel to shore power, permitting the batteries to attain full charge, and then (and while still connected to shore power) can the problem be duplicated?
