Question about running boat on the trailer connected to hose?

[GAGS]

Hey guys. I usually pump the engine oil out of our 2005 SANTE (EX 330) after a good ride.
This time around I needed to change the oil out of the water so I rigged up a hose connection on the inlet side of the strainer and shut the sea **** to stop the water going staright back out via the through hull fitting.
Engine ran up to temperature with a good flow out the exhaust and I got the oil nice and warmed up.
However, as well as the water coming out the exhaust I also noticed a very decent flow of water coming out where the prop shaft exits the hull under the V-Drive.
Can someone let me know how the water was being directed down thier as it has me guessing? Also if it is shaft lubrication why such a (relatively) large amount
Thanks

You have a "dripless" packing feature. They call it dripless because it doesn't drip into the boat like the conventional model. It actually does drip (or flow) but from the inside out. Water source is cooling water. I do not know the required flow rate.

Mine does the same thing if that is any comfort.

The flow of water by the propeller shaft is normal.

It you are laying the boat up for the winter, you should also change the transmission, and the V-drive oil.
