Good thoughts on this already posted:
#1. Probly the box, not you. I'd go for the warranty claim on the ignition.
#2. Boating itself, is NOT a source of stress. NOT boating is.
#3. Trailering sux anyway. Time for a dockominium or other solution.
#4. Redundant kill switches do sound like a good idea.
#5. Doctors are paid to be conservative, and their insurance liability reinforces it.
#6. If / when I die, I'd LIKE it to be on my boat!
