Thank for the input , grease arrived.
Checked prop and no damage , load of rope and fishing net around prop , cleared it all off , no movement on shaft so prop seems fine.
Engine mounts seemed OK, no unusual vibrations or sounds.
Shaft alignment looks OK.
Shaft couplings and flexible joints all look OK.
Took grease screw out and forced grease in past the jet of water spinning shaft by hand , that slowed the drip right down , ran engine in gear for 5 mins and repacked .
Thankfully now no dripping at all .
I thought about removing the front off buy was not brave enough , I thought water would piss in.
