b)
If a hose ruptures and no replacement hose of that size is aboard, a number of quick fixes are possible.
I Wrap with cloth, and tape, clamp or wire in place.
I Wrap with rubber sheet and secure.
I Slip a piece of hose with the same inside diameter as the outside diameter of the ruptured hose over the
leak and clamp in place.
I Split a larger hose, wrap it around the leak and clamp in place.
I Wrap repeatedly with tape.
I If there is sufficient slack, cut off the ruptured end and refit the hose.

THROUGH HULL FITTINGS
a)
If hull fitting carries away and leaves a hole through which water is pouring, see HULL LEAKS.
b)
If a valve is leaking around the stem or at a bolted flange, attempt to snug up the packing gland or the flange
bolts. If this fails to cure the leak it will probably be necessary to replace the stem packing or flange gasket.
A leak on the system side flange can be repaired by shutting the valve and draining the system. If not, the
repair will need to be done with the boat out of the water. NEVER LOOSEN THE PACKING GLAND WHILE
THE BOAT IS IN THE WATER.
WARNING
ADJUST SHAFT GLAND WITH ENGINE SHUTDOWN AND GEAR IN NEUTRAL.
c)
The stuffing boxes for the main propulsion shafts and rudder shafts should have a few drops per minute as
normal leakage to lubricate the packing. If leakage exceeds 6 drops per minute, it will be necessary to turn
the packing nut slightly to stop the leak. Some glands have two studs on them. The nuts should be
advanced evenly. Make adjustment slowly and watch results before turning any farther. Rotate the shaft by
hand to see that it turns freely.
