The marine boxes are sealed and potted for water resistance and vibration.

You're paying extra for the USCG certification.

Yep, we use the 6aln's and mount them on our own aluminum plate with a seal. Much cheaper.

MSD 6ALN

"The MSD 6TN and 6ALN ignitions are the ultimate choices for superior performance in harsh racing conditions. With sturdy vibration mounts and CD circuits encased in a clear two-part silicone elastomer, they are virtually vibration-proof. A specially designed, weathertight, 6-pin connector meets NASCAR's 20-6.1 ignition wiring rule and provides a tight, positive locking connection with individual seals to keep dirt and moisture from each connection. The 6TNs are equipped with a special 4-pin connector that plugs directly into an MSD soft touch rev control, while the 6ALNs have a built-in rev control. These rev controls are adjustable with plug-in modules, and will save your engine from overrev damage caused by missed shifts or driveline failures. They'll work with virtually any 4, 6 (even-fire V6 only), or 8-cylinder engines. "

Summit Racing has them for $311. http://store.summitracing.com/egnsea...5&autoview=sku

I like these becuase they have a built in rev limiterso you don't have to pay extra for the "soft touch". However, we remove the rev limiter chips, even on the marine version, because we have had problems with them on occasion. The box works fine withou, you just have no rev limiter.

As a well known driver said to me this summer " rev limiters are for amatures". I tend to agree. Do you hold the throttles open when the props are aired out? Are you running off the top of your props without backing off? If so then you NEED rev limiters.
