Help. Radar Cable Pass Through

[ddsailor25]

I need to pass a Raymarine radar cable with factory installed connectors through my cockpit fiberglass wall. Both sides of the cable have 3/4" connectors on it and the cable is about 3/8" thick. I purchased a blue sea cableclam for this, but i wasn't aware that it's just a solid piece of rubber that requires me to drill a hole in it. In order to pass the 3/4" connector over the rubber seal I'll have to drill a hole about that size and I question how much the rubber will compress to seal over the much smaller cable. What am I missing here? I thought these were made so that we don't have to cut the connector off and then rewire below decks.

It depends.

If the radar is on the mast, you will probably want to cut the cable and put a terminal strip inside the boat so you can pull the mast.

If the radar is not on the mast, take a look at the cable clam. If you can put the connector through the cable clam with the rubber seal removed, then you do it. The next step is to drill a cable-sized hole in the seal and slit it radially on one side with a razor blade so that it will go over the cable. Reinstall the seal in the cable clam and everything will get watertight when you compress the cable clam.

Drill a three eighths hole in the middle of the rubber and then take a razor knife and cut out where to the edge you can open up the rubber butt and around the cable clamp together it will compress it and it will not leak

I am in the process of doing the same thing. Be aware that cutting the cable voids the warranty.

Thanks for your help. I wasnt sure if cutting it with a razor blade to open the hole and get the cable inside would still make it water tight. Now i know. My radar unit is mounted on a pole so there is no need to cut the cable voiding any warrenty. Thanks again.
