Well, zero speed and altitude is what you would expect once the vehicle has come to rest at sea level (and sea level it was, wan't it?).
Are the Sergey's DeLorme trackings public? What you would
not expect is that the DeLorme sends a signal after ditching. Or rather, while the tracker may continue sending position (given that it is waterproof) you not not expect that the Iridium satellite
receives any signal sent from a tracker that is covered by water or otherwise has not a 100% clear view of the sky.
That's why in case of satellite trackers (Spot, deLorme, Spidertracks), the last known position is typically several minutes old.

Quite right. The other symptoms reported of his mechanical problems are also not consistent with belt clutch failure. So I would agree that it might have been zero speed
before ditching, which as other posters have pointed out suggest spatial disorientation in zero visibility.
