    4.3 MPI EFI Stalls on idle/when shifting out of gear

    New switch installed, boat runs perfect now no stall tendencies whatsoever. 3 seasons later this was a $40 15 min fix in the end🤦‍♂️

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    Been changing drive lube every season, always looked good. Short season around here, boat is planned to go up in coming 4 weeks with no further trips planned. I will probably only run it to check the switch when it arrives.

    Then I’ll just do cap and rotor now based on your advice. Will pull the drive once the boat is up for winter.

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    While waiting for parts, on to the next issue. I have a squealing/screaming sound, like a bad pulley bearing but from the back of the engine that started this season. I originally assumed it was from the drive joint/nut that hasn’t come off since I bought boat and probably needs some attention...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    I think this confirms it! I ran the boat with the switch bypassed, jumper cable between pin 1 and 3 on the connector according to a Service Bulletin I saw one of you link to in another thread. This allowed me to run it in gear all the way down to hot idle at 630-650 RPM without any stall...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    Gotcha, I believe it is open when depressed. I should then be able to jump the end of the harness contact, fire up the engine, go into gear and see if it will run better at idle. I’m guessing going into gear will be more rough when the switch is disconnected and isn’t killing the engine as it...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    I will order a new switch thanks guys! I can’t reliably tell if it is broken or not by measuring it with the multimeter, it does close and open when I press it manually but seem to be more sensitive than it should be.

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    An update after I have run the diagnostics. I get the following errors if I run the engine without stalling it i.e. just idle: 94 Pitot pressure low 75 Fuel level 1 circuit high 119 Steering Circuit low 104 Lake/sea Temp circuit high 130 Trim sensor Circuit high I think these are unrelated to...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    You live and you learn… Yeah that is why I initially was skeptical to a drive issue as well. I just recently learnt I can get a hold of scanner, had I known that from the beginning I might have started in that end. The progressive nature of these issue over several seasons seem unaffected by...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    Awesome, thank you for taking the time! I can borrow/rent a TechMate pro scanner, it will take me like a week or two to fix that though. I get that the scanner would indicate faulty sensors, but would it help rule out a sticky shift cable as well?

    Maybe I’m just overly cautious, I don’t like my serial number being searchable:)

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    OM631XXX I have analogue gauges which are a little hard to read, it idles strong at something like 750-ish rpm. I’m currently unable to get it to idle in gear, the lowest I can go in gear without stall is 1100. A few weeks ago it would idle fine in gear once you’ve shifted but it has gradually...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    I was down to the boat today to try to figure out a good way to diagnose if it really is the lower cable binding without any luck. The plunger type switch engages when shifting but really difficult to tell if it is touched when the engine dies. Anyone able to give a hint to what I should be...

    4.3 MPI EFI Stalls on idle/when shifting out of gear

    Thanks! The drive is coming off either way this winter for maintenance. Any trick to troubleshooting? Read somewhere to disconnect the upper cable and try to shift by hand?
