I have an 86 Bayliner Caapri with a small 3/4 inch tear in the transom seal. It happens to be just below the water line. The leak is not at all severe. The auto-bilge pump never turned on the last time I took the boat out. Is there any strong adhesive that will stick to rubber? I realize if there isn't I'll have to pull the lower unit off. Will 3M 5200 work? Thanks.
