You'd better believe it! In short, the screened hole in the base keeps vapors from entering the distributor and in turn keeps sparks from getting out into your gaseous engine room. The distributor cap must be of the non-vented type for the same reason. Fire prevention is obvious, especially in a boat!

The marine advance curve is usually different than cars as marine engines are operated at up to 100% of cars doing the same work at 20%, due to water resistance, of course. Marine engines are normally fully advanced around 2500 to 3500 RPMs, even though top RPM will be greater.

The vacuum advance canister is eliminated on modern marine engines as it's just not necessary to have two types of advance for the operating reasons above. Removing it leaves a void in the distributor housing that must be plugged airtight for reasons above.

What about boarding inspections at sea or lake? You forget to put in the drain plug, or many of the reasons below. The USCG or Sheriff can legally confiscate your vessel and passengers if at least five things are not legal for marine use: the distributor, fuel pump, alternator (generator), carburetor and flame arrester (air cleaner).

We are aware of the fact that installing our HEI electronic distributors in 383 thru 440 Chrysler engines requires grinding of the cast iron cylinder head for distributor clearance. This is due to the fact that HEI distributors are larger in diameter because of the reliability & performance capabilities built into these distributors. The spark plug gap alone is increased from .035 to .055 so they have to be larger. The 65000 volt coil (stock is only 18000 when new) is built right into the cap of this unit, making it a bit taller too.

These are a true marine performance distributor. If you are not willing to take a rotary file and a drill motor to make this distributor fit, better stick with your old 1970s points distributor, but you’ll be doing it with great sacrifice over ours!
