Hey All,
1996 25HP Johnson Tripple (J25RML_e_C.... or something like that, off the top of my head)
Motor runs good, then dies with minimal explination... often restarts immediatly after, one pull, sometimes I can get it before the boat really stops... Sometimes it won't run at all. Yesterday, no spark in the moring. Let the motor sit in the sun for 2 hrs. Spark came back, fired on first pull... later on, out on the lake (in the sun) won't start. Pullin the cord every 10 min or so as we drifted and rowed to the boat launch (caught 3 nice jack along the way
), Get it on the trailer and fires one pull... so, Its an intermittent no-spark condition...
What can I check. I don't have a wire diagram. Thinking possibly a short on the kill-switch still, maybe iron filings on the magneeto. I've got 4 wires from the mag (2 orange 2 brown) and I think 5 wires from the flywheel area for timing I think. I don't know how to test the mag or the ignition timing wires. Everything goes to or comes from "the Black Box"... ECU? ignition box? whatever you want to call it... I haven't touched the ECU yet, thinking of pulling my fly wheel off to check for metal burrs on the mag but don't know what else to check next time I'm in the "no-spark" condition. I dont think wires/plugs is the problem, the plugs look good and all three cylinders loose spark at the same time so wires are probably no the issue...
Also, removed the oiling system, and running mixed gas... Originally thought the boat was choking/bogging (over injecting oil)... minor detail...
