The water pump kit I got for my 1989 70 contains a gasket whose outline is the exact same shape as the bottom (metal) plate of the pump, and the inside is open. The gasket is not shown on any of the diagrams I have seen, and my factory manual does not mention it. It's a standard paper gasket - the only thing I can think of is that it goes between the lower plate and the gearcase. Should I use it? If so, do I need to coat it with gasket sealant?
