new trolling motor = less power?

[DJD]

Are you sure it is a 12V motor? I would think that for 55lbs. of thrust you would need 2 batteries, 24volts.

I have a 55# Minn Kota at 12volt. They can just draw down a Battery quicker than a 24V system.

Does trolling motor paper work show current draw? If not call tech support and get that info or if you have an Amp meter read it that way.The old one might draw less then the new one? Insure the connections are clean as well.

In the end it can only be the battery (is it a deep cycle?), wire size or trolling motor. Maybe a little of each.....
