What performance ignition does everyone run?
I've got a MSD box that is going out and was told that if I plan to run MSD I should always carry a spare because they ALWAYS go out. Marine box or not they can't handle boating. He suggested that I just go back to the original merc. distr. set-up. Im running a 502 and gonna put a blower, probably a 10-71with just 8psi boost, on it. Nothing crazy but I want plenty of room for power improvements later. I was wondering what most of you run?

The 6AL is coupled with a MSD Coil, Wires and Stock Merc TBIV Distributor and 22* advance module. IMO simplicity and reliability at it's best.

Stay away from DUI, I have DUI and am changing them out, shaft and star wheel were not attached securely causing erratic timing and I detonated three pistons ! Fixed that and advance weights came loose destroying cap rotor and advance module, lots of fun running on one motor for 25 miles!

About 15 years ago I ran a 6 al. Second time out it took a crap. I took it apart and a componet had broken off the board. I replaced it with a 6m the marine version and have never had a problem since. Be sure to connect the power wires from it directly to the battery. I also heard it's best to keep them as short as possible. I mounted mine on the transom right by the battery so the wires are only maybe 15" long.

What He said^ and stay away from the new stuff,MSD sold out to China which sucks,I too need to find an alternative.

I'm running DUI's...have run them in the past with no issues. I see quite a few of them on stock and performance boats here and in the Caribbean.
I have run Mallory and MSD in my drag cars...they work great in a dry predictable environment but I am dubious about their durability offshore. I ALWAYS carry a spare conventional distributor with me running back and forth to the Bahamas...there is no way I depend on any of the exotics out of site of land.

I also run DUI's unless you are supercharging or running crazy RPM's, I honestly don't get the need for fancy boxes and such. A stand alone distributor is all you need. I think they are pretty trick little pieces. The post above is the first problem I've heard with them, that is an unfortunate case I'd guess and a real bummer! I originally put an MSD on it that promptly died, though I've always had good luck with MSD's on my performance cars.
