More misadventures :-)
We took the boat to Alviso a.k.a. the City of the Stink, and had a fun time in the Alviso Slough.
Anyway, we got relaxed after a while, and my two friends started eating their lunch, at which point I promptly grounded the boat. The motor was stuck in mud, and the tell-tale stopped peeing. I shut off the motor immediately to avoid overheating, used a paddle to unstuck the boat, and dropped the anchor to keep the boat at deeper water.
While my friends kept eating their lunch and laughing at me, unaware of the possibility that they might have to paddle the boat back for 2 miles, I frantically slapped the water intake with a sock soaked in water to clean the mud. I also used a beverage straw to clear out mud from the tell-tale outlet. Thank goodness that only blowing was required, not sucking ....
With the motor back in order, we went out for a short spin on the bay. On the way back, we went over a part that was pretty shallow, and the motor hit a big sting ray lying on the bottom. I was sitting at the bow looking backwards, and saw a huge wing flapping in the boat's wake. That was quite a scene.
Back on land, we flushed the motor for a good while. Today, I flushed the motor again with a garden hose and the pee seemed pretty strong. Hopefully this means I don't have to open up the lower unit and clean out the water impeller.
