How long will an Electic Trolling motor run on a single charge?

Question

Say a 24V 50pound thrust motor pushing a 14ft aluminum boat, transom mount at top speed with high quality deep cycle batteries.

Answer 1

100 km

Answer 2

2-4 hrs  depending upon wind, currents, and laden weight of the boat

Connect a solar charger and get about 15-20% increase.

Answer 3

Probably a couple of hours at full chat.  Maybe 6 hours at "trolling speeds".

Answer 4

Just guessing and interpolating from a 16 ft fishing boat, but I would say about 3 to 4 hrs. Turn down the speed and you will increase the time exponentially.
