    And just like that, it quit.

    2019 Mercury ProXs 200 4s #2B597099

    About 930 this morning running down the lake around 4500 rpm and many miles from the launch the motor goes into full tone alarm and guardian mode. I look at the vessel view and it shows fault

    Critical Engine Sensor
    Shift position from shift actuator A and B difference
    Shift position sensor is not working correctly.

    So I shift into neutral and the motor is still running while I figure out what to do next. I put it in forward and have no forward gear so put it back into neutral and turn it off. I try to restart it and now it won’t turn over. I call Don and he gives a phone diagnosis of a potential shorted/faulty harness.

    So here I am now miles from anywhere with my wife and 8 year old step daughter in the boat. I get on the trolling motor which thank goodness was still pretty much at 100% and after a couple of hours we make it to a boat launch. I called a friend of mine to come and pick me up and take me to my truck so I could come back and load my boat. Luckily there was an empty slip and it was a safe populated place for my wife and step daughter to wait in the boat. This all started around 9:30 and finally got off the water around 3:00. Thankful that it happened early and was amazed the trolling motor batteries never crapped out because it was a long trek.

    I am in the process of working on when to get it to Don for repairs and it looks like 2-3 weeks out on parts so guess I’ll be working on home projects for a few weeks.

    Bummer. I see that you are located in TN. FYI, I just found out that Tellico and Fort Loudon lakes have a volunteer group that helps stranded boaters (called TBART). If you call 911, they will contact TBART to send someone out for a tow. I have not had to use this yet.....

    Should be a recall on that sensor... easy fix...
    all you had to do to get home, was disconnect battery to motor cable for 1 min, reconnect and drive to ramp...

    Hmmm I will go out to the garage now just turn the key to the on position and see if the alarm goes away. The battery has been isolated since Friday evening. Also it’s in some gear position other than neutral as the prop won’t turn.

    The computer is seeing that it is in gear and won’t let the motor start.

    Well dang ended up needing another part so had to leave it with Don. Hopefully it won’t take too long to get what it needs. Thank you again Don for the prompt and thorough mercury service and your attention to detail.

    Great news Dave!

    I agree, Don is the man and I wish he was close enough for me to take my boat to him.
