Which Sikaflex?

[Richard Selman]

...product would be best for sealing the stainless attachment plates and through transom bolts of my A-frame? The plates and bolts are on the back of the transom and may be under the waterline at rest.

Sika 291 is the traditional choice.

I use 291 for all thru hull transducer installs, does what it says on the tin.
