MerCruiser 810845T Alpha One Oil Pan Basin Reservoir 4cyl 140hp 3.0L One-Piece 60hp The Hydro-Mechanical Unit shift housingsItem Details MerCruiser Part number 810845T 810845 Great shape, very clean oil pan, HOWEVER, The baffle is cracked at the bends where it attaches to the side (see pictures) You could tack weld them back on, or you could just leave it as is. I would say about 75% of oil pans that we remove have this issue, and it is a common design issue even going back to the 2 piece oil pans since the 60's. These were pretty much used on all 4cyl & 3. 0L 140hp 181CID
