Can anyone guide me through the process of testing for power to the power pack and coils. I'm not getting any spark. Thanks for any assistance out there.

If you're not getting any spark at all the first thing to do is disconnect the large red cannon plug and test for spark again. You first have to determine if the problem is on the motor or in the boat harness and wiring.

Remember -- once you disconnect that plug, just test for spark. Don't try to start it. If it starts, the only way to shut it off is flood it.
