How do I tell if it's a power pack issue or higher up?

[QUOTE="Frankenfish, post: 475523, member: 25701"] Thank you, most people describing a bad power pack online mention it running "rough" rather than not at all like mine is. Now that I re-read some of them, I'm guessing that they are describing boats with multiple power packs and more than 2 cylinders so that some cylinders keep firing and running the motor. That tidbit about Force motors quitting all at once is helpful! I did check the kill switch to ensure it didn't get mashed in the kill/short position and found it working as expected. Got continuity to the ground when depressed and continuity stopped when released so it left me confident it wasn't stuck on and bypassing the plugs. I've been using Leeroy's Ramblings and he describes if everything else has been tested, then try the power pack. Is there a simple way to test the flywheel coil or sensor to ensure it's not higher up before trying a new power pack? Any chance it's the stator? If anyone stumbles upon this thread, I'd highly recommend you give Leeroy's Ramblings a read for older Johnson 9.9 and 15hp motors. https://www.leeroysramblings.com/Johnson%209.9_15.htm [/QUOTE]
