Thanks so much for the input. Just want to update and increase my chances of reliability while out to sea. The thunderbolt system is a good system it's been on there for 32 years on the south shore of mass. the single wire system seems to be the right direction. Again thanks for the reply...
Has anyone replaced the thunderbolt iv system to a one wire hei distributor. Thinking about Davis unified ignition. If so were there any installation problems and any tips you may have. Thanks so much for any info. JT
