I've had two Minn Kota's, didn't keep either one long enough to wash the new off. A Maxxum 55 on the Classic and a PowerDrive 55 on the LT25.
Didn't get enough stick time on the PowerDrive to know if I love it or just like it. My unscientific opinion is Gheenoes are not the straightest tracking boat after you kill all power. So I was always having to play with the motor to straighten us up. I never did get the drag chain out and use it.
I could see where the PD would shine, just to move you to where you need to be in the current with the chain dragging.
Will the 48" be enough or should I go with the 54" shaft

Lets here your opinions and wisdom on brands and types.
