Looks a bit like butyl. The more solids in the material used the less effective the depth sounder. Use silicone or epoxy.

Re: SILICONE to mount in-hull transducer?

For those that have installed the P79, can I ask how you rate the performance? I have a Raymarine DSM300 that I bought last year but haven't installed it yet. My choices for transducer is one of the through hull designs, the P79 or the much more expensive M260.

I've always leaned toward an in-hull transducer since I have a solid glass hull. I have plenty of room for the larger M260, but at 5x the price over the P79 it seems like it might not be worth it for an extra 400W of power.

So, do you like your P79's or do you wish you had more power?

Have you been able to compare to through-hull type transducers?

Also, what type of module and display to have it attached to?

Is there usually air trapped in the silicone in a tube?

It's easy to get bubbles in silicone. That is one reason I use epoxy.

Re: SILICONE to mount in-hull transducer?

Ill be doing this soon on a cheap garmin fishfinder....mounted in hull

Ill be going the mineral oil in a pvc tube cap way as it is completely "removable" jajaja not that it needs to be...learned this trick from you guys on here.

I hate clear silicone and anything remotely related to it like 5200 etc...much rather use manual methods

Ill post an update next year! jaja

cheers

Re: SILICONE to mount in-hull transducer?

never understood why people want more power out of their depthfinders..what you need is the perfect spot to mount it perfectly upright so it shoots a clear uncorrupted line down to the bottom...

more power will only give your more ability to see larger depths...not what you need a depthsounder for

or is there more to it? my studies have shown me to look more at proper installment over "power"
