I think you're right and its body flexing that encourages leaks,more so when the sealer has dried out. I had an old merc that let water in round the screen and tried a marine sealer that was painted on and dried like a thin clear varnish. It was fine for a few days but then started letting water in again.Looking closely you could see where the sealer although sticking well to the body,glass and rubber had split open along the seams showing there had been movement between them.
