I have not had any trouble with my 2001 225 EFI for some time now. I have had OTHER problems but not the Merc. My EFI has let me down two times this week. On Thursday, I backed the boat down the ramp and nothing happened. I got the motor to trim so I could put the transom saver on but it would stop working, too. I took it home, monkeyed with it for a few minutes, tightened the wing nut on the positive side of the battery and everything started working. I bumped the key this morning before we left the house and the motor turned over. It started right up at the ramp. Everything was okay after about 3 hours of fishing. I ran the boat around the lake to cool us off and I thought the motor sounded odd. Turned the motor off and tried to start it again. Nothing. I dropped the trolling motor and took us back to the ramp, which was close by. Put the boat back on the trailer and went home. When we got home, I made sure the shifter was in neutral and made sure the kill switch was engaged. The starter battery has 13 volts. I put my load meter on it and it says it is good. Nothing. I can hear something at the motor but I am not sure what it is. I will get up early tomorrow and start checking things out. There is a fuse on the side of the motor that I will check. I will check cables. After that, I am up for suggestions.Any input would be appreciated!
