"Neil,

Check the lanyard and switch. Ignition module could also be to blame, but I'd check the cheap stuff first. Pop the distributor cap, take a look at the rotor and contacts. Make sure neither one is damaged.

Good luck

"I'd check the engine shift switch. After 5 years the linkage gets worn and the kill switch will not let it start.

Switch is near the engine or on the transom where the shift linkage terminates. To check try moving the shift handle around and check to start after jiggling the shifter. You can see the micro switch and push it down with the engine in neutral. I'd bet it starts right up.
This switch kills the ignition when the engine is shifted, making it a zero torque shift. they constantly fial and need re aligned, try it. You could also check the high voltage output from the coil, if it is zero when you crank....the kill switch is usually the cause.
