Ok,<br /><br />Sorry but I don't have the serial# with me right now, but I was wanting to know if anyone has ever replaced the speed coils in the lower unit of one of these bad boys....<br /><br />It a good little trolling motor, has a 12/24 switch on the foot pedal and three speed settings on the dial, also on the pedal.<br />My problem is I have lost both the low and medium speeds no matter if I'm running 12v or 24v. The high speed setting works fine however at any voltage... I have replaced the speed setting switch on the pedal and also the toggle "activator" switch but the same problem remains.. So it has to be the coils in the lower unit I assume, and based on an old marine tech I talked to...<br /><br />I believe this is a 1986 motor... Worth repairing or should I dish out $600 for a new Motor Guide?
