6 inch fiberglass exhaust system coupler has fractured, leaking exhaust and water into bilge. It is a joint coupler between two rubber bellows. The rubber bellows are clamped to the fiberglass coupler with two standard hose clamps on each side of the bellows. I have a new coupler ordered. Does anyone know if a sealing material is spread on the fiberglass prior to assembly, or are the bellows simply clamped to the fiberglass? The old fiberglass coupler seems awfully rough on the surface for an effective seal.
