About This Product

Planning a rebuild on a GM Marine 3.0L or 181 OHV L4 engine? This lower gasket set from Enginetech has you covered. Part number M181CS-A (interchanges with CS5719), it includes all the essential lower gaskets plus both the 2-piece and 1-piece rear main seal options—so you can choose what fits your setup. Brand new in its packaging, this kit is perfect for marine mechanics, boat owners, or anyone doing a bottom-end refresh. Not a universal fit, so make sure it matches your engine specs.
