I hate intermittent problems. 3 times this week, I went out to start the boat and had no spark in the number 1 plug. I go back an hour or so later and it has spark. Its not the plug wire (I switched with another and the problem stayed on #1) and I put a new coil on it to eliminate that possibility (and still had no spark). I check all the wires for bare spots and could not see any. If I start it and take it out for a run without the #1 plug firing it will attempt to fire once in a while but not always. Once it started firing and ran great for 30 mins until I parked it. Today I started it, no spark. Came inside to read forums. Went back out an hour later and turned the key and it had spark. Rode it around for 20 mins with no issues. I turn it off with spark, go out the next morning and no spark ....All the grounds look good.....Arggg .... Is it more likely that the trigger or the switchboxes would have an intermittent issue? or neither? Thanks in advance
