Running NMEA Backbone -- Epic Fail

There are several areas in these boats were electrical and plumbing run through various bulkheads, stringers or other structures. Sea Ray usually sealed them up with globs of silicone or similar sealant.

I have been able to work a corner loose on the bulkhead between the cockpit and the cabin to run all sorts of wires.
Which corner, and any pics?

I assumed this was a big no no with exhaust fumes and such.

I have found it easier sometimes to drill a new hole. Pull everything in place and then seal it with clear silicone just as SR did without using quite the "blob." As long as you seal it back, no harm done.

If you don't have a pull cord already in a conduit here is a trick I learned from a electrician buddy. Tape or tie your cord to a plastic grocery bag and stuff the bag into one side of the pipe. Once you get the bag in the opening go to the other side and suck it through with a shop vac.

Yep...I learned this trick from my electrical engineer brother...worked perfect on 200' of buried conduit I had to run for my Starlink setup at a rural property...
 
Find a different route to snake it through. When I had to run the wire to my helm for my underwater lights, I took the hard top side panel off that's behind your head when seated in the cock pit. That allowed me to pull the wire up from the engine room, then back down behind the seat, into the gunnel and forward to the helm. I had to then take the molded plastic cubby out from beside the helm seat to route into and behind the helm switch panel.

Greenlee even makes a Super shop vac built just for that. Only works on conduits with no wires in them, though.

In the fiber optic world, we used a product called coreflex (had a kevlar pull line included in it). It is a sleeve that's pulled thru the conduit (usually 3 or 4 of the sleeves). The fiber cables go thru the sleeves. Keeps everything neat and tangle free when working around live fiber cables. I would imagine it would work on a boat, too, as a standalone flexible conduit if the pull cord is present.
 
So good news, bad news. I was able to loosen the jam enough to pull the cable back out. So it's free. Bad news is, I can't for the life of me figure out a way to run it. I'm at a complete loss.
 
Have you spit on it and rammed?

That usually works.

How come everything in this thread sounds dirty?

why don't you cut the end off and pull just the cable through then install a field installable DeviceNet connector afterwards. My long-run backbones have field installable connectors. I used these but Anchor and Garmin makes them also -

Happy to report the thrill of victory.

ended up with an inspection camera and traced the transducer wires. Sea ray couldn’t have buried the end of the tube any deeper. Basically along the hull wall behind everything. Once I was able to get my hand on it and pull it out into the open it was a piece of cake from there.

On to the next one, pulling new radar cables. :)
