I got my Minimono a month ago. Unfortunatley, I have not been able to enjoy it as the wire drive shaft comes loose from the coupler at the engine within 2 seconds of entering the water. I followed the instructions, tightened easch side progessively and no luck. I even tried epoxy! - No luck. I guess my next try will be to solder the wire shaft to the coupler. Has anyone else had this problem and are they any solutions, thoughts Ideas?
