"Graham,
Sorry I am just getting back to the CD (switchbox) question. Like Fastjeff stated, the only difference in a single cylinder 2 stroke and 4 stroke is the revolution of the flywheel. One revolution for a 2 stroke and two for a 4 stroke. They both require a voltage of around 20,000 volts to fire the plug. The coils for both have the same resistance as do the triggers. The charging coils, I am pretty sure, are the same. I know that Tohatsu stated that they are different electrical, but I do not buy that. So I purchased a CD (switchbox) unit for a 4 stroke and put it in my 2 stroke. They are both the same in electrical wiring, the only difference, is the 4 stroke unit is ¼” longer. This was 1/3rd the price that I would have to pay for a 2 stroke CD. I have run it for over three hours up and down the Satilla River with no problems. I will let you know more when I get more hours on it. Thanks for all the replies.
Rick"
