Just installed new lower unit, test ran at ramp, and pulled out. I have a milky chocolatee oil discharge from a weep hole by the prop, is that normal?

Unburnt fuel il mix draining from the gearcase cavities. Very normal.

Its still honey colored. So you're okay.

Yup, both are normal. If when the gear/oil turns white and looks like a milkshake that means you have a leak. Otherwise, you should be good to go. Make sure you replace the small crush washers on the DRAIN/VENT screws as they are a one time use only item. You'll want to use 80-90w Hypoid, Outboard gear oil as well. You should be able to find it any boat store/wal-mart for about $5 a quart.
