Probably is Blowby...any leaking up top around the valve covers?

No, coming only fro the dipstick.

Make sure your crankcase isn't over full. It's easy to do...that can cause oil to climb out of the pan at high RPM with a high volume/high psi pump.

Looks ok against the stick.

Will be changing the oil this weekend for winterization.

Will be running 15-40 Mobil 1, not sure what the previous owner used (guessing Quicksilver from the bottle left in the boat).

Trying to figure out what people are doing to deal with the issue, as I see blow-by is a common issue on 502's. Mine are MPI's, with a PCV valve (new).

Thx,

Eric
