That is an intake Water jacket and inspection port for an inline 4 or 6 cylinder for Mercury inboard engine. the box on the top with the 4 bolt holes usually has a screen in it to filter water flowing in to the engine. On the bottom there is a drain hole so you can flush the engine of water for winter storage. In most cases there is a petcock valve or a metal plug depending on the size it may be a 3/8" npt or a 1/2" npt . See reference below. I hope it helps.


This is as close as I can come to the exact model if you look at this link you will see a similar one on this engine. All Merc and Merccruiser inboard sterndrive engines are black.

Does not appear to be related to water or thermostat housing.


this is missing parts but it looks like a reduction gear box

Thank you. It looks more like one of the other opinions, either an exhaust elbow or water pump for a mercruiser. If possible, could you maybe find a similar one online so that I can accept it faster?
