Fiberglass Marine Waterlift Muffler / Wet Exhaust Water Lock - Used

Used fiberglass marine waterlift muffler (water lock) for wet exhaust systems on inboard diesel or gasoline marine engines. Rectangular hand-laid fiberglass body with an offset top inlet and side outlet, both approximately 2 in hose stubs — the classic waterlock geometry that prevents raw cooling water from siphoning back into the engine. Gelcoat is scuffed and stained from service but the body shows no visible cracks or repairs. Application: Inboard marine wet-exhaust systems using ~2 in ID exhaust hose, typical of small to mid-size marine diesels and gas inboards. Condition: Used take-off, sold as tested visually only. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
