I have had a hand control variable speed motor, but never a foot
controlled one. How do you control the speed on a foot controlled
variable speed without it being difficult to use?
I have enough trouble controlling direction with my foot, much less
speed at the same time.

I did call a local expert and they said
it was a knob just like the fixed speed one on the 5 speed models. He
said it was not free wheeling so it stays on the level you put it on.
That makes since. Plus with the variable speed model you get there
patented maximizer technology that extends trolling time on one charge.
Unless somebody says that they have had a bad experience with the 55, I
think that is the way I will go.
Thanks
