Hello all.
What, if any, sealant is used to bed / seal this foam gasket?

I have a new quicksilver foam gasket for the gimble to transom seal and I want to make sure I seal it correctly.
Can I use 4200?

Thanks guys!

I followed the directions on my last install and went with the gasket alone. So far so good.

It was very difficult for me not to want cake it with 4200.

The last one I did, I used weatherstripping adhesive to hold it to the transom assembly then a little grease on the gasket on the transom side..

Had to remove it recently due to breaking the sh!t out of the gimble ring.. NO leakage was evident..

mercury sais to use bellows adhesive on the transom assembly and dry on the transom,i have always done it that way and never had a leak.

Thanks guys!

before you do any of this, It is best to make SURE your transom cut out is the same thickness all the way around and take a straight edge to it as well ----- exterior and interior areas that bolt up the transom assembly and somewhat past. Without checking it 100 percent, that can be a leak source - existing one and or a leak(s) waiting to happen.

Many builders lay up thickness thru out the transom area is not perfect on every boat plus the area can have uneven spots both sides or one side ---- exterior and or interior transom area . . It is very wise to check NOW.

4200 is almost as strong as 5200!

I think it's a little over kill for something that needs to be removed again.

Just a little bit of bellow adhesive in the corners to keep it in the groove.
