I have a small 16ft with 40HP 4 stroke. I think my 'idle' speed is 1.2mph(no wind). I just need to know if I can do some 'cranking' for crappie without spending a pile of money on a remote/GPS trolling motor system to pull cranks in the up coming months. I plan to put rod holders in the rear of the boat, and have my fishing partner watch the 4 poles directly behind the boat while I keep up with the boat watching for depth/cover. I may get a 12-16' pole to hold while I'm keeping up with the boat to keep me occupied. Does anything about this make sense to you guys/gals?
