Yamaha 4 stroke "making oil"

[Rmarsh]

I changed the oil and filter in my f60 over the winter and added the 2.6 qts. of oil. Several checks of the dipstick to be sure the level was right. Returned from first trip out...checked oil...several times ....dipstick showed oil level waaay above hatched area. Drained it out and it measured it thinking it would be more than specs but it wasn't over. The oil has a darker color than it should being only a few hours use and faint gas smell??? Read up on possible cause and solutions.

Anyone have similar experience?
