[C320-list] Clearing thru-hull obstruction

[jim brown]

A friend gave me a pair of locking pliers specifically made for clamping hoses. They have smooth pivoting jaws with no teeth that remain parallel when closed and the pliers lock when clamped on the hose. I find lots of uses for it including when winterizing. Bet you could get a pair at Harbor Freight for next to nothing.

I'm aware of the back-flow issue. I thought I might just use vice-grips to
collapse the hose to prevent back-flow and not have to undo any connections.
Then, using the winterizing "T" back-flush with a hose. 

The number of really good suggestions offered, even later on, is very
appreciated. I've not yet decided how I'll approach the matter; but starting
with the simplest is probably what I'll try first.  Thank to all.

Warren,
If you do this, you may run the risk of the water back flushing into the
engine-especially if you have a clog at the seacock. Your best bet is to
remove the hose at the water pump and use a shop vac to blow out. Another
way to do this is connect a short extension hose to the short section of
hose at the water strainer so you can keep it above the water line. Another
potential reason for your problem is the O-ring on the seacock itself. They
can get stiff and cause this type of problem. Unfortunately this was my
problem at my macerator seacock on my 320. You can plug from the outside and
service the seacock while in the water if this turns out to be your problem.
Hope this helps...
