Fishfinder Transducer - Silicone or Vaseline?

Should I go with the silicone and if so what type would you guys recommend? I understand I need to be careful with airbubbles, so if there is advice on this I am all ears.

Scuff the bottom side of the transducer with some sandpaper and press it down all the way. Do not wiggle it around. Let it set up over night and you should be good to go.

Same with fittings. I was able to take off my Scotty mounts also with a bit of work.

As for type, I've used marine grade, household and so on - all seem very similar to me - as long it's marked 100% silicone.

When I bought new roof racks, I was forced to place my yak on the hood upside down. If you are in this situation and you like to leave your yak on the car for any extended period of time (even one day), the Vaseline will turn into a soupy mess on a hot, sunny day and the it is unlikely whatever you use to keep the transformer down (duck tape), will lose its hold.
My buddy has had the same transducer taped up with Vaseline for 4 straight years and has experienced no issues...then again, he places his yak right-side up on his truck.

You can make a deep holder for the vaselein by cutting out a piece of closed cell foam from an old boogie board. Drill a hole in the middle big enough for the transducer using a hole saw. Glue the donut in place using goop or spray adhesive. Then place the transducer inside the donut of foam in a bed of vaseline. Then take the plug out of the hole bit and slice a piece off creating a cap that you can insert inside the donut and on top of the transducer. A slice from the side allows you to run the wire where the center bit had been in the plug.
To test locations for a transducer you can place the transducer in a plastic bag with a little salad oil and moveit around in the boat while checking out the signal.

The answer is yes. That is the reason why I use Goop rather than a permanent application, as my fear was that I'd have to buy another transducer if I needed to move my fishfinder to another yak. Although it takes a little work, the Goop will allow you to remove the transducer less any possible structural damage to the yak.
