I am replacing the port head gasket on my 1985 Evinrude 90 4 cyl VRO Model # E90TLCOS I have a replacement gasket from Evinrude # 318358 (from an Evinrude dealer)<br /><br /><br />The original gasket appeared to have some blue gasket sealer on it. (It came off real easy).<br /><br />The replacement gasket is a different material (dark grey). The dealer told me to apply gasket sealer to the gasket (where it covers the water jacket). Should I use Permatex non-hardening?<br /><br />Gasket package says BRP US inc. Evinrude / Johnson<br /><br />Also, the gasket says to place the tab at the top and arrow pointing to the exhaust cover. Is the exhaust cover on the inboard side of the piston or the outboard side of the piston (port bank)?<br /><br />Sorry for the stupid question, I am still waiting for my manual.<br /><br />TIA<br />Ol Yank
