I have a 1986 50hp Yamaha 2-stroke (50ETLJ)

I have black slimy oil leaking out the exhuast hole with excessive smoke.
Creates a slick in the barrel when idling.

I found a faulty O-ring on the fuel filter that's leaking fuel when I prime the
gas (Part# 93210-37M25-00 O-RING). Can this cause excessive unburnt oil to come out the exhaust? OR should i check something else??
