[QUOTE="Pappy, post: 442131, member: 3278"] [size=5]Respectfully...you can take the boat wiring harness and throw it away and the engine should still have spark. A blown fuse will not eliminate spark. The only fuse on the engine is for the start and trim functions. Spark is eliminated by connecting the Black/yellow lead to ground. That grounds the ignition system and stops the engine. Your engine's ignition system is a magneto style. Once the flywheel is turning it generates its own voltage/current needed to produce spark. Check the black/yellow with an ohmeter to verify. [/size] [/QUOTE]
