I have been using the MSD Digital 6 Plus box (Pn 6520) since Oct 2006.. no issues yet.. (Knock on wood)..
Also run MSD crank trigger, MSD Pro-Billet distributor. MSD Starter. and lock timing out at 34..

Wouldn't recommend it . I had a piece break off the circuit board in one and left me stranded. The marine version is filled with a polyurethane resin to keep moisture out and everything in place. It's worth the $150 more.

On the 6AL non marine box the bottom is only riveted to the main case by 4 rivets on the corners. There is no kind of seal whats so ever between the 2.There is no way they could ever be considered water proof. The marine version is completely potted with polyurethane resin so there is no way the circuit board or any of the parts inside can get wet and are secure from vibration and shock. My 6AL failed from shock and vibration in the middle of the first season on the boat. Replaced it with the 6m and have had no problems for 8 years now.

Like i said some what waterproof! you must have got a lemon..mines not mounted on the engine,its mounted on the transom away from the vibrations..maybe thats why its lasted so long....Per the tech at msd he told me that all the msd components in the box's are sealed in polyurethane..

Ive had both 6m's and 6al's. track records for both for me is about the same. They work most of the time, but sometimes they just fry on you for no apparant reason. I have friends that have had more 6m problems and replaced with 6al and lived.
My experience is use either one of them and either run a ready to run dist. as your mag pickup so that it can be jumpered in the event of a failure or, what I do is keep a spare box in the boat and wire the box with a quick connect harness.
