exhaust housing cover plate question

[mountainboy]

1978 Johnson 20 model#20cr78c<br />Does it need a gasket or seal around it? I just drained my l/u oil and it was a light green/milky color. I was troubleshooting the problem: Changed washers, tightened screws well, but was wondering if this could be the reason for water in fluid(besides seals needing replacement) if the gasket or seal is missing. Thanks

Hi Mountain<br /> No the gasket on this cover would have no affect on your gear oil. How ever there should be a gasket installled on this cover. Presure and vacuume test your lower unit, this will tell you where your problem is.

OMC recommends their gasket sealer on both sides of the exhaust cover gasket. I don't thnk this has anything to do with your L/U problem, either.
