I have a Mercury 1986 2 stroke 25hp tiller style motor, and it died on me while on the water. When I got home i visually checked the wiring and saw no burnt areas. I unscrewed the spark plugs and cranked it but no spark was seen, i disconnected the kill switch on the throttle handle but nothing. I'm lost without a manual, and suggestions.

Re: No Spark at all

No points on this model ..


Chink...
Read and follow the advices from the CDI troubleshooting guide..
Can be found here.

Are 4 probable causes..
Spark plugs/ plug wires/ coils > not likely as as 2 identical part goes bad at the same time..
Stator > possible
Trigger > possible, but unlikely
Switch box > my money is on this one ..
