      Got a question concerning a more modern motor, an Evinrude 38 spl. Not sure of year, early 80s or later 70s.
      Hit a stump.
      Now the motor will not run at anything more than an idle. If throttled up from idle it will rev briefly then die.
      Carb has been rebuilt.
      Fuel pump re built.
      Gearcase re built.
      Any suggestions?
      Thanks

      PS have started my 1954 Evinrude 25 hp fix up!
      So stoked to be putting it on a newly acquired 1952 alumacraft 14 footer!!!

        Post some pics of the 54 evinrude. I have the same motor and will be starting a rebuild sometime this winter. As for the 38 spl. I don’t have an answer. Bryan

          It would be hard to relate hitting a stump with not running above an idle. But who knows?

            Having trouble locating any info on a 38 spl. Are you sure it is a 38? Maybe a de-tuned 40 commercial motor or something??? Got a picture?

              Ahhhh! Sparks fly off the flywheel now that it’s dark out!
              It’s a J28elcds.
              80s.
              I think ’85.
              Yea, something got all shook up!

                A J28 model is virtually the same as the same year 30hp, except the 28 does not have the VRO oil injection system. OMC had a 28, 48, 88 and 112 special during those years. I once owned a 112 spcl – great motor. Not sure what the problem might be but obviously sparks flying off the flywheel needs to be investigate!

                  Ahhh!
                  It’s a 28! 1986.
                  Could not see where sparks came from.
                  Shut it down REAL fast!

                    Check the woodkey under the fly wheel.

                      Thanks for all the input.
                      Pulled the flywheel.
                      Key is in good shape.
                      The “mag plate” (I put in quotes cause it’s called something else on these newer motors) is very loose.
                      And laminates of the stator are shiny, even scored, as are the magnets in the flywheel. There is a fine black powder on everything under there.
                      Could the stump strike (at WOT) have jarred the motor so much to have damaged that mag plate causing it to wobble enough to interfere with the electrical system causing the motor to die at anything more than idle?
                      Long sentence!
                      One more question, is it possible for the strike to damage the lower crank seal enough to cause the motor to die at anything more than idle?
                      Would a damaged lower crank seal prevent the motor from running?
                      Thanks.
                      Y’alles knowledge never ceases to amaze me.

                        In my opinion, I still have a hard time relating hitting the stump to the mag plate situation. From my viewpoint, I’d say the looseness and wear has been going on for some time. Well ok, possibly the violent shake of the strike might have jarred the loose parts to a new position. Further inspection is required there. My wild guess is the sensor is ground to bits, causing the run/die condition.

                        Strike damaging lower crank seal??? Nah.

                        Lower crank seal prevent motor from running?? Nah, not from running at all or at high speed. Prevent it from idling properly, maybe.
