Hot out of the inbox 2 minutes ago. Not verified but passing along in case you are waiting for someone:

Just got a call from my husband that the throttles on the Water Taxi
are broken.  The captain is taking it out for a cruise right now but
would not let passengers aboard.  They are hoping to have it fixed by 6:50
p.m.  Just wanted you to know in case there are people waiting for
someone to arrive on the Water Taxi (like I was).

8:30 PM UPDATE: From the same reader (thank you SO much!):

My husband just got home….but on the bus. As of 7 p.m. the Water Taxi was still out testing the throttles in the bay. Therefore, the 6:50 never took off. Don’t have any more info.
