Wondering what you all would recommend for keeping the wiring to my graphs clean.

 

My boat came with some plastic right angle grommets, but once I added the networking wires for the front of the boat and a back up transducer wire they didn't fit anymore.  My fix since the hole was there was to just wrap the wires and fill the hole.

 

The Ram mounts were in the wrong position and not capable of holding 12's and allowing adjustment so I am replacing them with some Nerka mounts.  Just about to drill the holes for the mounts, but would like a nicer way of making sure the wires stay clean.  I couldn't handle the cracked black plastic mat, so I am open to about anything.

Got all the rubber and glue off and filled the holes to start fresh.  New seadek like material from Amazon.

 

Just need something now to keep the wiring clean as well.

Look up boat wiring clamshell

 

Or you could try some waterproof cable glands.

Thanks.  Those have all helped improve my searching!

The through-hull wiring kits made by Hobie,Yakattack and Wilderness systems are pretty nice and should also work.

THIS!

You might look into desk grommet also.

 

My Garmin 9SV came with one of these. Actually been searching online to buy more just like it, but no luck.

I ordered some Garmin grommets.  Should be here tomorrow.  Hope they work ok.  If not I will order something else.

Take a look at marine Multi Deck Seal?

Some great ideas here.  Thank you all.  After changing my search terms to match what you all shared I found these: 

 

Which when drilled out fit my cables tight enough to be mostly waterproof, but still allowing it to come out vertically.  And I realize I will get some water in during a monsoon, but it isn't anything a little caulk won't fix once I am sure that I have the wiring finalized.

Between the new mounts and the upgrade seadek pad under them I think it turned out great.
