What about wire nuts with silicone in them? Made

I dunno, the ABYC hates wiring nuts for any
application on a boat. I wonder if the vibration has
something to do with it.

Our current boat electrical system has lots of wiring
nuts, thanks to DPO... everything works so how bad
can it be? A different DPO (or perhaps the same guy
after a few years of relaxing standards) used a lot
of twist-N-tape which has a high failure rate.
