Ayuh,.... The only Hei distributors I've ever seen rated for marine motors is those by DUI,....

Good question, as the shift interupt on the TBIV interrupts the signal from the pick up.
I'm assuming you are using coil in cap HEI ? There is a merc chart that shows which wire with the external coil (voyager) HEI.

I just run the HP HEI from summit, remove the vac advance w/block off kit, use the correct wire connectors, but never used on a alpha..they work great and you can add a digital rev limiter from petronix with a simple dial for the RPM, been using them for years, at least they do not corrode like MSD
