Trolling motor problems

[56 crestliner]

I bought a Minn Kota Maxxum Transom Mount 55 LB. thrust yesterday. Today i mounted it on the boat and hooked it to the battery and the prop wouldnt spin. i played with the controlls and i had to go up real slow and the prop would spin very slowly and when i tried to speed it up it would die. The battery tester on the motor says the battery has a full charge. im i not getting a good connection? OR is it the battery? the battery is a cheap deep cycle we took off my dads boat when he got it. I didnt put it in water while trying to use it, Does the water lubricate it? Help

Thanks

Shouldn't need to put it in water to make it spin better. Sounds like an issue with power. I would take the battery in and get it tested properly. That's the easiest thing to check and fix before you start thinking about other possible reasons.

well i just called minn kota and they said it is probably not getting enough volts. And if that doesnt help to take it to a service center, my question is, is if a service center will charge me even though the motor is 1 day old

If the battery ends up not being the culprit, then you should return the thing, if you you bought it new.

try a different battery.

if its still the same, return it for a new one

i just got 2 55s myself, and im pretty happy with them

Well i tried a different battery and it did the trick, the battery that did work was actually smaller than the original one i tried. I left the one that didnt work on the charger for a couple of hours then it to worked. I think the problem is that the battery can't hold a charge.
