Default Problem with 300x or not ????

2003 Spectre 30 with twin 300x outboards.

One has wet fuel in the exhaust and the other one does not.
I first noticed it when the fuel was on the lower gear case. When I dropped the lower units (broke prop shaft) I looked up into the exhaust and saw it was wet and the other one was not. Any ideas?? motors have 70hrs on them. Its like one is running real rich.

Thanks

Best way to tell weather its running rich is to look at the spark plugs.
Is the boat freshly out of storage?
Are both engines running same RPM?
Do you have the smart craft gauges where you can see temps and fuel flows?
I wouldnt be too concerned with what you have found initially but I would keep looking to make sure.
