Trolling motor question?

Hi folks, I finally deсided to spend some money and order an electric trolling motor for my boat. I cannot say, that I am a fan of trolling and I cannot live without the motor, but I kinda wanted this thing so long.

These 2 were selected, based on my own online research I did online. Both brands seem to be okay, but I am still kinda concerned, so decided to post here and ask your folks opinion before I go and buy something.

I wish I had info for you I don't use trolling motors on my tubes, but I am sure we will get some info here soon. I think I might know some people that can help as well I will see if I can get them to sign in and give there 2 cents.

You say for your "boat" could you be more descriptive?
