We broke out the light weight motor boat today. A riverhawk with a 5HP motor, runs all day on a couple of gallons of petrol.
I’m using this as an example to show what the paths from an etrex 20 look like with google earth:
and with FoxtrotGPS:
FoxtrotGPS is more than a little less stable than Google Earth, but shows what is available from sources other than the “sage of mountainview”.
The maps show an afternoon trip. The difficult thing on this lake is dodging the buried logs. The engine is a tohatsu 5hp, and we’ve found it runs better with 10w-40 formulated for older engines.
