Take a dive and see if your underwater thru hull is covered with critters.
chances are that you'll be able to clean it from out side. In case you need
to remove the valve from the thru hull pound in a bung to keep the water
from coming in. While your down there, check to see if your hull needs to be
scraped. Never take the divers word that they did a thorough cleaning with
out checking their work.

Hi,

Finally got that old hose off with a hacksaw and a fair amount of
flame. Problem is, I STILL haven't found the blockage! I usually find that
if the blockage is in the thruhull, opening the valve with the hose off
gives a blast of reverse water that clears it. This time, NOTHING! not a
trickle.

Obviously, I can't remove the thruhull without hauling the boat, so I'm
looking for alternatives. One thought - could the handle on the thruhull
be broken and the valve is just not opening? Seems to be doing
something... Or, I can get my Lady the semi-fish to dive under and poke at
it from the outside with a stick, making sure she doesn't leave the stick
in.
If that doesn't work, can I use the 1" thruhull currently used for the
head sink drain? Either T it, or live without a sink in the head until I
haul the boat.

Comments? Suggestions?
