Hello everyone, I have the above mentioned engine
SER # OG227090

Was loading boat onto trailer and it died at 3k rmp, was a bear to restart but it did and idled, I was launching the boat yesterday and it didnt want to start. Finally it fired and idled then all of a sudden it died and would not restart, pulled plug put on a spark tester no spark.

I checked kill switch.

I read here to pull black and yellow wire, nope

also tried the yellow wires to the rectifier, nothing

Please help I have a DVA I just need to know the procedure.

Of course I have friends heading here in the morning to go fishing and the local marina is 2 weeks out.

Thanks in advance Jack

I dont want to throw parts at it and hope, I was hoping that someone had the test sequence for the DVA and the paramaters.

Ok everything checked out with the exeption of the low side of the stator, Paramaters are 3250-3650 ohms it was 450 and dva was 180 v and the actual was 22, I am assuming that it is bad would I be correct or should I continue testing?

Sorry for the long delay.....work sucks....

Put on a new stator, finally the right one three trys later, Merc had a bunch of updates and addendums on this model.

We are up and running again!!!!!

Thanks everyone!!
