Hello, first post. I am reinstalling the lower unit on my 1985 Evinrude 55 Commercial. My factory manual specifies sealing the lower unit mounting flange to the mid section. There were remnants from sealer when I removed it.
I don’t have a problem with using sealer, but is it necessary? The housing of the lower unit fills with water by design. It’s two machined surfaces. Here is my question. Is it necessary to apply sealer to the mounting face of the lower unit? Thank you.
