Thanks guys. Difficult to get the padwheel moving when the boat is in the slip and there's no current lol. I can try sticking my outboard motor in front of the boat and gunning it to get the water flowing... or I can get in the dinghy and try to reach under to spin the wheel manually...
Before I do that - I have a digital readout of my NMEA 0183 sentences so I can analyze the readouts line by line. I don't even have a readout for "0.0.0" on the speed (or any speed data at all) I'm wonderring IF the padweel isn't turning, it will literally give back NO data / sentences at all? not even a "0.0.0"?
