GPS speedo for a boat.

Was ok last fall, stored over the winter, and now the gasket has
expanded.

Something with the Teflon grease I'm using on it is my guess.

Has anybody seen this before?

Any way to make it shrink back to it's normal size?

I made mistake of greasing an o-ring on my water filter housing with
Vaseline and it expanded too much. I easily shrunk it back with careful
heating with a heat gun.
