Hey guys. I have a duramax drifter 3 trolling motor that cuts to about half speed when I put it in the water. It seems to work fine when its out of the water. Also when it cuts to half speed and I turn the boat it cuts out completely. If I turn the throttle to 0 and crank it to full it goes full throttle but right away cuts to half or less speed. I charged the battery just before I used it and it's hardly been used. Any help would be greatly appreciated.
