conversion to electronic ignition

[McGillicuddy]

I came across an older Seacraft recently and decided to bid on it (the sickness continues). Oh, yeah, the Seavette is still available (not begging for exodus help yet, but wife ain't any happier)

This one is an i/o with a I-6 mercruiser.
I presume it has old school ignition and was wondering if it could be converted to electronic ignition reasonably cheap and what the performance/maintenance benefits might be. I believe it is a 70's 250 cc GM w/MerCruiser 160 although I have not seen it in person. Any thoughts on this.

Thanks.
