    Couldn't shut down my Volvo TAMD40B this afternoon. Had to plug the air intake to turn it off. Anybody have thoughts on this? I suspect the switch.

    Did you try turning the key back the other way one click?
    With the engine off have someone move the key switch while you listen to the stop solenoid.

    Yes, I tried one click the other way. Then tried the flybridge switch. Was by myself. I'll check the solenoid when I have someone with me. Thanks

    I can't remember if those are power to stop or remove power to stop.

    No Volvo experience but I would be staring down by the injection pump looking for corroded wires or a relay / solenoid with dirty connectors.

    It used to happen on my Volvo 41A about 20% of the time. there is a spring loaded plunger on the fuel pump. Push it in and it shuts off the engine. It does what the "shut off solenoid" is supposed to do.. No need to starve the engine for fuel or air. I learned the hard way..googled it on my phone when engine wouldnt shut off. Its not on the lift pump, its on the BOSCH injector pump. Wish I saved the picture of it.

    Yes, sold her in the spring. Nice couple from RI. No dickering just, "yup, Ill take her".. He knew Cape Dory's so we didnt need to do a sea trial. And I did show him how to shut her down at the injector pump if the stop solenoid doesnt work. That solenoid was probably the one thing I didnt address on that engine. I would open the hatch to check the engine at the end of the day when I shut down so reaching over to push that lever was no big deal. I think the solenoid was $700, but easy to find..

    My stop solenoid burnt up twice on same engine
    If the key is left on by accident they burn up
    At least mine did

    What Skeets dad said. Push the plunger down on top of the injector pump. Have a TAMD 60 series. Happens every once in a while. Usually when there is very low water in the slip, and I kicked up a lot of mud and want to shut the motor off as quickly as possible as to not suck up the mud in to the sea strainer. Or when I'm winterizing the boat on land, and I have just sucked up the last gallon of the pink stuff.

    Goody, Let me qualify by saying Im no mechanic... but this worked for me for a long time. I dont have a picture of the injector pump on my boat (sold) so I googled it. This is an injector pump for a TAMD41A. Its mounted on the engine in the same orientation in the picture. You can see that little lever (in the center) that pivots.... I recall mine had a spring on the bottom. ON MINE, when I pushed the bottom of that little lever (aft), the engine shut down immediately. IMG_1186.JPG

    This is the kind of problem a decent reliable Bowden Cable would remedy. The cost would be more like $15 >$20 instead of $700. I admit I don't know this particular engine but a bowden cable was a standard emergency shut down feature on several engines in the past.

    Some 550 heading twine with a ring on the end would work just fine. Buddy used to have that with the ring sticking out of the engine box.
