The Subconn BH4F has a 7/16x20 machine threaded shaft 3/4 inch long.  
You can either drill a hole and bolt it in place, or thread it into a 
thru-hull manifold appropriately machined for 7/16x20 threads.

Check PSUBS or Subconn website for detailed info on Connector BH4F.  If 
you can't wait for delivery and use something from a local supplier, I 
recommend you wire it as per Design Guidelines for Personal Submersibles 
Section 3.1 at 
http://www.psubs.org/cgi-bin/guidelines/chapter.cgi/guidelines/PSUBS/DG 
since David should now be wiring his projects according to the standard 
as well.
