I know the older stuff was BRUTAL, I had several
MSD7AL2's that would "sit" over the winter and in the Spring suddenly not work? I had good luck with the 7AL3 for the brief time I had it, then switched to a MSD 10 and it worked awesome, but, wasn't all that great on the "street".
I seem to remember years ago being able to wire a "bypass" in my MSD6A so that I could just run without the box if I was ever stuck, cant remember how I wired it, but, could look it up.
I dont know if the new "Digital" stuff is marine certified? But, its probably much more reliable than there old stuff
Just my .02

The 6AL "N" and 6an are, but not the 6A or 6AL. The "N" is for nascar guys I think. Talked to MSD last week about this, as one of my marine ones took a crap. Says Im SOL. They will rebuild the 6A or 6AL ones he said. 
"N" series potted with epoxy

The one that took a crap on me this summer was a 6M-2 marine box, purchased in 1999. 12-13 years out of it, Im not complaining. I think the main key with these boxes, is mounting them on the transom, or away from the engines, or if you have to mount on the engine, use the rubber feet MSD sells to isolate them from vibrations.

I've had mine go bad several times. Everytime it would go bad is after the battery had been drained. One time I ran the stereo til the battery was very low. The last time we had a power inverter hooked to a battery to run a lap top which Eddie was using to tune the ECM's. I think one of the things that kills them is Alternators trying to recharge a very discharged battery. They always go out the next time you use them after the incident.
