depth sounder replacement

[texsun]

I made the decision to replace my 2000 yr old Lowrance 3500 with a new Faria Chesapeak SS. The SS is an updated depth gauge that comes with an InHull Transducer. My question is can I simply use a putty knife to remove the old Lowrance Transducer, sand, and clean the area ...and glue down/silicone the Faria Transducer in?? If the putty knife is not cool...please let me know the best approach.
Thanks in advance!

no, not used by Jesus, he walked on top of the water, regardless of its depth.

Would advise against the use of silicon in a transducer install.

Silicon is a sound deadening material. Epoxy propagates sound magnitudes better. Better sound transfer, better performance

Do you have any TESTED data results of the squeezed out Silicone. I do. No difference compared to a transom mounted Transducer. The small boat has 2 identical fishfinders. No difference. When both are on at the same time and different frequencies.
1 in the Aluminum hull. The other outside the transom.

The silicone will fail, in my 60 yrs of boating, I have never saw a successful silicone use. Then when it fails, it is very difficult to get anything else to stick in that area. No silicone anywhere near my boat...

Got it done! Been down there for 20yrs....not 2000 ) I have a 2005 Larson 208.
I looked at the original set up and thought 'should be pretty straight forward'...
This Faria IN HULL transducer has a plastic 'well' that it recommends using sillicon to stick the 'Well' to the hull...then you pour RV grade anti freeze (looks like a few ounces to keep air space out) in the 'well' ..and then you mount the transducer into the well.
And they advise I conducting a couple of test to determine the 'best location'
Has anyone has any experience with this?

Thanks
