Instead of investing in an expensive flow meter, that has to be adjusted to the actual flow, keep a record of your fuel burn at every refill. Not the engine hours each time, then you can develop short and long term actual fuel consumption plans. You would need to do this to set the flow meter anyway as I understand the system setup.
I’ve cruised to Desolation and beyond in gas powered boats since the 1960’s and with proper maintenance and safety habits there were very few issues. I suggest you read “The Curve of Time”. It’s about a family cruising the length of Vancouver Island in a gas powered boat…in the 1920’s and 30’s. It will boost your confidence.
