Maybe half close your inlet valve to reduce the flow somewhat. You would have to gauge the extent of the water ingress of course, but it would be doable wouldn't it ?.
Definitely doable!!
You would have to fiddle a bit with the intake flow - also you don't want to be sucking air when the bilge is empty so you would have to adjust that flow as well.
I haven't had to use this so it's all theory but worst case it should empty the bilge until I could stop the leak.
I also have an old 12v water pump (from my fresh water system) with hoses & leads attached ready to drop into the bilge if needed.
This is on top of my main 12v bilge pump, with ear-piercing alarm, then the secondary 12v is on as well & then there is the manual pump!!
I'm paranoid about sinking!!!
