Looking for any help in clearing an AC through hull from inside the boat. My diver is trying to get here today but I'm not sure he will get here until tomorrow.

The flow is about 20% of what it should be and my pump is laboring as a result.

On our boat, the strainer is horizontally mounted so it is a right angle to get to the through hull. Coat hanger did nothing and I can't get a screw driver in far enough to clear the barnacles.

Any advice will be greatly appreciated!
