oil smells like gas

[Last Call]

I have about 6 hours on the motor a 75 HP Yamaha 4 Stroke. I noticed
last night my oil smells like gas.

is this normal during break in

it is not normal once rings are seated properly
It is something that happens to a 4 stroke motor running too cold, over propped, or *****ing(low RPM operation) too much.

Or a bad fuel pump could cause it too

Not normal but a frequent occurance on 4-stroke engines. I had 2-quarts of gas in my F250 at 7.5 hours. Changed oil and ran motor 4-6K RPM, gained another 1/2 quart in the next 12.5 hours. Changed oil at 20-hours, ran engine normally and have not gained any in the next 17-hours.
