Howdy folks, first post on this forum (bringing my new baby home this weekend). I'm really curious to see how you mounted your Minn Kota!
Here in the Pacific Northwest trolling motors such as the Minn Kota I-Pilot are almost mandatory for successful fishing for kokanee -especially trolling against the wind. Folks either mount the electric robot on the bow or have a TR1 robot installed on the rear kicker.
Since you already spent the big $$ on your robot an inexpensive addition is to install an extended skeg on the motor similar to the one on the link below. (Mods: not trying to steer towards this specific brand/product-just an example) About 1/2 the folks around here make their own out of a piece of irrigation pipe and 1/4" aluminum plate or you can go the route my pop took on his Minn-Kota Ultera and have one made for about $100. The impact on performance can't be over stated. The skeg is essentially a rudder that will help "plant" your bow in place when trolling into the wind. The amount of RPM your ele motor needs to keep course is about 1/3 of normal which = much longer battery life. If the boat also has a kicker you can set your thrust/speed with the little engine and steer with the bow mount-often with ZERO rpm from the motor at all.
