OK you motor heads..... was out on my mariner 4 today and was pushing up stream on a slow moving river( dam wasn't generating) I pushed the boat a for a good hour on speed 5, then mainly drifted back down. I had no problem but I started wondering... if when having to travel a larger distance (I'm only using a MK 30#,gas isn't an option) is it any more efficient to hurry up and get there on highest speed....slow and steady on 2/3.....or doesn't matter, just use the same math as normal- motor amps vs AH of your battery? I'm also aware various other factors come into play....current, wind, etc. But what's your idea in general...for the sake of it assume flat water no/light wind
