Can an electric 12-volt 1-hp trolling motor with a 100ah battery push our 4,500-lb. boat to that distant island (2-miles) and back? That was the bet. And we won. In fact, it pushed us along at 1.5-knots (nice trolling speed) for 5-miles, and it still had juice remaining.
We never fired up our very thirsty 4-barrel 250-hp Mercruiser. First time. And we feel virtuously green because, as everyone knows, electricity comes from the pixie dust raised by the stomping golden hooves of dancing rainbow colored unicorns.
Okay, we used a lithium battery. But still, that’s a lot of barge to push through the water.
We would now call it an e-boat, if WWII history had not already taken that name.
