I have an Aluma Craft Classic 16 (16 foot boat). I would like to replace the Minn Kota Powerdrive tolling motor that I currently have with an Ultrex, primarily to have both spot lock and foot control. The Ultrex is obviously much larger than the Powerdrive. Has anyone installed an Ultrex on a 16 foot boat like this? Is an Ultrex too big for a boat like this? I believe the Terrova would have spot lock and foot control and appears to be smaller than the Ultrex, but obviously it doesn't have all of the features of an Ultrex. In short, I would rather have an Ultrex. Curious if anyone has had any experience or thoughts on this. Thanks.
