This is reproduction of the D Water Pump Cover also know as the Propeller Shaft bearing carrier. We found that when using the original bearing carrier under a D or E Mod engine the factory carriers would shear at the forward plate. To solve this problem we increased the radius of the fillet between the cone and the plate which seems to have eliminated this problem. We have made these out of T-6 Marine Grade 6061 Aluminium, even drilling the locator pin hole in the plate.
