Before you do anything else drain the gear lube and inspect the magnets on the drain plugs. If the lube and magnets look good then pull the outdrive and inspect the gimbal bearing. You can reach up with your hand and insert a couple of fingers in it and spin it around. It should spin smoothly. Also inspect the u-joints while the drive is off and the driveshaft splines and the splines in the coupler.

I agree that draining the fluid would be best. I live on a lake and the boat is on my lift, so draining it isn't the easiest. Checking the magnets is always a good idea.
My next Questions: What size are the threads on that drain plug so I can make a hose for pumping it in?
2nd: How do I inspect the gimble bearing?

Do a search on converting a garden sprayer to an quick lube injector. I built one and it works great, I fill the entire drive in 5 minutes. Sydwayz has the best step by step, the thread is about 5yrs old.

If you just trolled around for 5 min, and didnt run the boat on plane or under load for any amount of time, I doubt you hurt the drive. Sounds like there was already a problem with the drive as mentioned(gimbal bearing or u-joints). You need to pull and inspect, then refill properly.
