Is their possably a vent hole in the lower unit wear the 80-90 gear lube is ? Their is a little hole on the top and I have dots of oil coming out into the water from this hole.
Or do I have a leak some wear else, there is water getting into the oil also,maby a washer leeking on the drain and fill plugs?

Put some new washers on the drain and fill plugs and try it. You could also have it pressure and vacuumed tested.

I believe you are referring to the drain hole, but post a pic to verify.

There may be oily water exiting there, which is unburnt fuel/oil mix. Are you sure it is gearcase lube? If so, may have a leaky shift rod seal or drive shaft seal.
