I have an 80# thrust Terrova for a little 16' aluminum mod-v. It's powered by two 100 ah lifepo4s in series to get 24 volts. I troll but I only go out if wind is under 10 knots. It seems to work fine for an hour or so but then starts shutting down. I do notice that autopilot usually keeps the motor speed on about 8, which seems excessive for such a small boat.
So I would like to know if this is normal.
What are you all running as far as thrust? What batteries do you have? How long can you troll?
