Hi Dick,
Jerry and Dad (Gordon) both have Terrovas on the boats. Both are 24 volt with 60" shaft and I-Pilot (with foot pedal). We've never had cable driven trolling motors so can't compare. However we had no problems with the Terrova and find them easy to use (even me). We've talked Dad into upgrading to the Ulterra though for the self-deployment (don't want to lose him overboard wrestling with the trolling motor in rough water). He has one "on order" and was told they are 6-weeks out for delivery. We are hoping it comes before our trip to LOW. He will be looking to sell his one-year old Terrova in case anyone is interested--only used for one week on LOW! Looking forward to seeing our LOW Family July 4-10!
