Default Installing B260, which sealant ???

Going to install a new B260 w/high speed fairing block in my new 28 Seaworthy.
I'm wondering which sealant to use, 5200 or a marine silicone/sealant.
I'm thinking 5200 for a nice heavy bead for both inside and outside halves (after I cut for the slight angle needed) of the high speed fairing .
Then a big bed of marine sealant or silicone for the transducer.
Any suggestions?

You can use 4200 if you want, it will easier to remove should ever need to. Lay out the 4200 and start by placing the back of the transducer down and move slowly towards the front. It is very important that get NO air trapped or you'll have problems. If you do the 4200 will allow the ducer to come up with little effort.

"No air trapped"
It sounds like you are referring to the M260 shoot thru.
I'm installing the B260
Very large bronze thru hull, with even Larger high speed fairing block.
Can't see how trapped air will come into play with a thru hull ! ;?

Don't use silicone in any application that always stays wet. It will eventually break down & disolve.

I use 4200 Fast for all my X-ducer installs.

I do have a B-260, but it's flush mounted in my hull.

I was talking about the the B-260 and we do the same thing as warthog. I agree that over time the silicon may come loose but if the ducer ever fails good luck with the resin.

Ron, just use boat life caulk. 5200 and 4200 is over kill. You will get in trouble with either if you need to remove later. Great boat BTW

5200 fast cure is the only thing I have ever and will ever use, I don't know about anyone else but when I do anything on my boat I overkill it to prevent future problems.

The chemist who invented 5200 died and went to heaven. God is a boater, and rightly rerouted the chemist to hell. The Devil is not a boater, (even though a large percentage of his customers are) so he knew right away what to do with the Chemist. He is seated, almost within reach of an ice-cold gallon pitcher of the very best stuff ever brewed, with nothing to eat but salted pork rinds. Unfortunately, he sat on a dollar-sized dollop of 5200, and it will be at least a thousand years before he can reach that pitcher. So, rarebreed, 5200 *IS* a future problem!

4200 or LifeCaulk. No silicone below the waterline.
