Ok so here's the deal...my last fishing boat was a 16' Lund tiller. I sold that and got one just a bit longer and a bit wider. I got rid of the Minn Kota Powerdrive off of it because I like cable steer models much better. My last boat had a motor guide with a 45" shaft that I cudda swore was just long enough. The current Motor Guides switched the on/off and selective power switch around on the foot pedal. Therefore, I'm looking at the Minn Kotas. The Minn Kotas typically come in 42" shaft. 52" is available but with the mount they are GIANT. Does anyone out there run a 42" shaft minn Kota on their fishing boat?? I'm afraid in a chop it's just going to be a touch short. I understand there are rules of thumb in regards to trolling motor running depth but want to see what you alls opinion is. Thanks!
