3m 4200

[Sea horse]

I was installing a new transducer and was wondering is 3m 4200 enough water protection on a small fastener bellow the water line?

Both my B175M and TM185HW were installed with 4200. No issues so far.

I’m interested in some of the others say on this topic.

yes, that is the adhesive/ sealant of choice for your installation.

Yes

Ivory Original Stern Saver – Stern Saver Fantastic product. Very neat installation.
Used many times on my boats and my friends boats, especially if you like to update your electronics often. Your transom will thank you.

Yes......Use that.

I second the stern saver.

I now use 4200 for anything under the water line. It is tough and has plenty of adhesive grip. My B175HW transducer is installed with 4200.

When I have used 5200 in the past, I found it is a stronger adhesive. Makes removal a bear if you ever want to remove a fitting. Transducers will get updated over time so better to plan for future removal.
