I am a Minn Kota man. I have owned and used both brands, but none of them have been saltwater models, but my understanding of the saltwater models is that they are just sealed differently that the freshwater models. I prefer the feel, fit and finish and my perceived durability of the Minn Kota motors, I know others will say the same about Motor Guide.

As for specifics I think you should get at least an 80 pound thrust motor for the boat mentioned, maybe more. You can never have too much power, but it is horrible to have too little.

You getting a boat?

Lotta ins, lotta outs, lotta what have-yous
