No spark on 90hp Evinrude

[Nitro_Brad]

I have a 1995 Evinrude 90hp outboard that was running pefectly until it stalled and now has no fire to the plugs. I put new plugs in an still no spark. I thought I could see a slight spark on one plug but I can't be sure of that even. Anyone have ideas?

Re: No spark on 90hp Evinrude

In a shady area, remove the spark plugs to obtain the highest cranking rpm possible. Cranking speed must be approximately 300 rpm in order for the stator to energize the powerpack.<br /><br />Rig up a spark tester whereas you can set a 7/16" gap. Crank the engine and observe the spark.<br /><br />If no spark, or a very weak spark, disconnect the electrical plug(s) at the engine, then crank the engine via a jumper at the starter solenoid. If you now have spark, inall probability the ignition switch is shorted, in which case replace it.<br /><br />Let us know what you find.
