    Mercruiser 5.0 Getting Spark from Coil, but No Spark to Plugs

    Sweet! I'll try that out. If it doesn't spark what do you think that would mean?

    So just to check if I follow, I should hook up the spark checker to the coil wire and ground it out with the spark checker. Then use a feller gauge in the ignition sensor to test for spark at the spark checker?

    It wasn't bent down at all. I measured it with calipers after I installed it and before I put the new cap on.

    Gotcha! I wonder if I need to raise the tang even more than the manual said. That seems like it could be the issue.

    I used a timing like to see if I was getting spark. I'm unsure of the strength of the spark however. I did notice that it was intermittent when cranking. I did check the point of the rotor and it looked on point, but slightly off so I took the rotor off and placed it back on and it looked good...

    Mercruiser 5.0 Getting Spark from Coil, but No Spark to Plugs

    Hey everyone, long time lurker, but first-time poster. I’m honestly at a loss to what is going on with this engine and I can’t seem to pin down the issue. It is a 2007 Mercruiser 5.0 with a thunderbolt V ignition system and a Alpha I Gen II outdrive. Back in February I was backing the boat off...
