Many thanks to Chris and BT, as well as others who provided direction and advice. So far, looks good. A few more trials and all confidence will be back. Changed out the Ignitor Module, for the Ignitor II Module and boat ran fine. Coil was much cooler. Used the original 1.5ohm coil and then switched to the Flamethrower 3.0ohm coil. Both worked fine. Will let you know how it fares next week, on a longer run:)

The purple wire running to the choke is not a resistance wire, it's 'full feed'...
I've been misinformed. A Pertronix tech told me that is a resistance wire. However mine is missing.
Yes, I have ignition issues.
