I got a 60 hp mariner serial 0g185851(1995). It hadnt been started in at least 3 years. I put new impeller on it and new plugs. Cleaned it up and it started fairly easy. Only ran it about a min cause it was raining. The next morning before i went to laje i started it again and it ran about 3 min and just quit. The stator and trigger tested within specs(ohms and dva). Would this most likley be switchbox? Ive also tried with black/yellow wire unhookef and with both yellow wires to rectifier unhooked and no spark.the rectifier did have a burn looking place on it so i replaced it. If it matters it has red stator. Thanjs
 
i also noticed last night that the bottom ignition coil spark plug wire has a split in the boit so ive ordered that. Would just one ignition coil being bad cause no spark? I went ahead and ordered 3
 
I should have a used stator for that here that tested and ran fine, but it has been on the shelf for 15 years. 200v sounds okay anyway. DAD?
 
If its a red stator it should be a CDM style motor or if a kit it could have the adapter on it. If its a CDM style it does not have a switchbox as the CDMs are switchboxes

It musta been a kit. It does have the adapter for the stator(im assuming thats what the skinny black thing is attached to outside of swithcgbox housing with 2 zip ties) it does have a switchbox thats where i got part number for a new one. I dont know anything about the history of this motor other than i was told it hadnt nbeen started in at least 3 years. I got it free on craigslist from an old guy that was moving. Everything looks goid on motor, especially a free one
 
These are the switchbox i ordered from part numbers off existing parts

Tis possible switchbox failed but haven't seen many of this style do a complete fail,just a cylinder or two or midrange miss
 
Did I miss the trigger test results? Don't forget to test trigger in ALL throttle positions. Why? The wires move enough that they can break conductors and they still appear okay to the eye.

The trigger tested high on one of the ohms readings, but voltage tested good. I went ahead and replaced trigger and no change so i installed switchbox and still no spark. Only thing left is stator? I guess. But stator tests good on resistance and voltage. Any ideas?
