I have a 1990 Evinrude E48ESLESA 48SPL . I am curious as to whether there is a gasket required between the lower unit and where it mounts up to the intermediate shaft in the exhaust area? I've looked at the parts drawings and not noticed any there but since I'm ordering parts I need to make sure theres not one I don't see. If it's not necessary then I can get this unit together tonight hopefully and on the water tomorrow during the day. I'll be posting another thread about assembly questions on the lower unit rebuild shortly as well for those veterans that are willing to pass a little information along to a newby. Thanks!! D.N.
