A Sad Day.

[Wayne SW/MO]

Many aluminum boat transoms are wood/aluminum sandiwiches and the older ones aren't treated against dry rot forever. I don't know that this was a cause, but it has and can happen. Fortunately the first sign is when someone overdoes the throttle in reverse and sees movement that should be there.

No Wayne, the cause was the glass boat moving at 45 mph and striking a bridge pier that was slightly under the water, causing the motor to fly off the transom into the passenger.
