Can the hose on the shaft log be changed while the boat is in the water?

If you can have a diver stuff a sealant around the shaft from the outside first. I've heard of some folks using plastic bread bags for this while changing the packing in their stuffing boxes.
Sounds like a lot of work to me considering you need to uncouple the shaft from the transmission and slide it back. You also have to consider if there is sufficient room to get the hose assembly and stuffing box over the end of the shaft when it is disconnected.
