Author Topic:   1996 RAGE 15, OMC 115; No Spark on #3 Cylinder

Bigchrisf4i posted 08-25-2014 10:49 AM ET (US)
I have a 1996 Boston Whaler Rage 15 with the OMC 115-HP jet drive. I was checking spark and have spark on three of four cylinders. I swapped out the ignition coil as well as the power pack with a known good. I still have no spark on the #3 cylinder. To anyone who thinks they can assist in troubleshooting further: [is there] any way to check the stator or voltage rectifier? I'd like to mention the tachometer is not reading when trying to turn motor over. Thanks in advance.

I would replace the plug wires are re-try. If the new wires do not solve the problem, look at the optical Ignition System Sensor.

Plug wires were swapped out with known good when switching out ignition coil. I see the section which talks about the optic sensor. That is under the "No fire at all" section. Shouldnt I be in the "No spark on one bank of cylinders? Just checking for clarification before messing anything up. Thanks

The OMC service manuals provide procedures for testing the coils associated with the alternator, the spark ignition primary voltage coils, and the spark timing coils. The procedure involves resistance checks of the coils when not in operation, and voltage checks of the coil output when in operation.

Thank you all for the info, I found out what the problem was and for future help to others I will post answer below.
*After swapping out the ignition coil and power pack, the one cylinder still did not have spark, after taking it off again I noticed some black gunk on the ground of the ignition coil. The coil plastic and melted and was not allowing for a proper ground from the ignition coil to the block. After cleaning unit worked fine and spark was back. Didnt help that I checked compression after I had the motor running for 5 minutes to find 115,112,90 & 90.

Bigchris thanks for posting the "solution" to the problem always help full when original problem is taken care off.
As for your compression, now you know what you can do this winter, but in the meantime enjoy the rest of the season.
I once ran one of my old Chris-Crafts with 112/74/79/98 for a whole season, power was down but she started and ran fine.

I heard this winter is gonna be a good one so I will have plenty of time! Glad to hear you could run it for a while with less than perfect compression.

Yes Chris that is why we Northerners work on our boats/engines during the winter months as that gives us the idea that we are boating year around like our Southern boaters do.
New head gasket was all it took to get the old engine purring again.
