would be interesting to know if you have spark on any of the cylinders.

my guess is no.


do you have a kill switch lanyard on your control set? (have to ask this to cover all bases.)

I had a cdi box do something similar to this one time on a dirt bike, ran fine cold or till stopped then no fire to restart or really weak fire. Changed the cdi and fixed the problem. Just a guess? I also had a 1980 Johnson 70hp that had a no fire issue and it was the cdi box.

Check for spark at the plugs - all of them. Then trace backwards, i.e.; coils, switchbox/powerpack, trigger, etcetera.

Having happily lived with Mercs most of my life, and having undergone EXACTLY that scenario with a '92 XR4, my guess is trigger or switchbox. But that's only a guess.

My wife got rather upset when for the 2nd time we were 9-10 miles offshore and the motor wouldn't start 'til it cooled down completely. :-(

My motor had a bad trigger due to deterioration of the wiring insulation. During diagnostics, we discovered my switchbox wasn't very good, either. Changed those out and the motor ran perfectly another 5 years/300 hours before I repowered with a 90 Optimax.
