Sealant for transducer wire

[HVF21221]

I am replacing a broken transducer and the 1" hole and wire was sealed with caulk. I have a tube of life caulk from my front hatch re-seal job which does not leak anymore (thanks for the lead on the sealant guys). Should I use something more solid for this or life caulk would be ok? Thanks, Howard

above the water line that's fine. below 5200

Thanks, now I figure out where the waterline is lol.
maybe 5200 to be safe

I know this might stir debate….LOL

However I am one of those guys that use 5200

For most things :shock:

I just use a little braided fishing line 8)

Using a sawing motion to cut though it If I need too
To remove an item
I don’t go nuts with the stuff but I would rather feel safe :wink:
Especially if it is a questionable area

Another vote for 5200

BUT

1" hole is a little big to be filling up with just caulk if it is in fact below the water line.

I'd take a wooden plug, undersized, and would wet it out with waterproof 5-minute epoxy and do same with the hole. when both 'kick', i.e., are sticky to the touch, goop 'em again and insert plug into hole.

Presto ... permanent waterproof cure ! But you'd need to paint or cover exposed portion, as raw epoxy breaksdowns under UV exposure.

The reason I am unsure where the waterline is because I just bought the boat over the winter. This is one project I am trying to do before I splash it. The old owner provided the new ducer and I am just swapping out the broken. The hole is right under the motor bracket. And hard to get to from the inside. I used a fish wire on the old so I just need to pull the new through. I think I will make a plug that fills the hole with a notch for the wire then insert it. Then have it seat below being flush, then cover with 5200. I may make the plug out of pvc or something like that.

id put a clam shell over it on the outside and just goop it up good with some 5200. you can buy the smaller tubes at home depot.

Can you post a photo of the problem that you are trying to solve?
I'm having a hard time visualizing...

I agree with this if it is a 1" Hole :shock:
Wouldnt want that flooded out the boat one day :roll:

I would use all of the ideas, wet the hole with epoxy, wet a plug that is 1/4" smaller in length and 1/8" smaller in diameter, notch the plug for your transducer wire, put the epoxy on once while wet in the hole and on the plug and again as it thickens and shove it in the hole, Tape around the hole with masking tape and be prepared for some to ooze out both sides, , clean off excess epoxy, once dry I would fill the depression with 3M 5200 and cover with a clam shell. Sounds like allot but would only take a short while and provide good protection.
