After issues with my 2019 newly delivered Mercury Verado V8 250hp outboards leaking oil, crankshaft oil-seal replacement and finally one complete block being replaced under warranty, a sheen of fuel can be seen on the water.
A joint investigation by my dealer and the manufacturer was launched.
Mercury’s conclusion: “ all internal combustion engines have unburned hydrocarbons that are part of the exhaust. The sheen on the water is unburned hydrocarbons, not oil from the lubrication system. The engines are operating normally”.
Can other Mercury Verado V8 owners comment on this?
