So seacocks, what do I need to buy, mine are plastic and look old.
- - Compare the flex of the Stuffing box hose to that of the same size "wet exhaust
hose without wire". If they match then no problem. If yours is more flexible, then simply replace it with a same length piece of "wet exhaust
hose without wire."
- - Even if you have the yard do the painting, hang around while they are doing it and look skeptical and shake your head
every now and then. That will hopefully keep them honest. And you will either learn how it is done or how it should not be done.
- - If your thru-hull seacocks are "black plastic" they are probably Marelon. Go to a marine
supply store and examine them. The are ball valves normally in two pieces. The two pieces are screwed together to apply pressure on the ball valve inside. If they are over-tight the ball valve will not be able to rotate. If they are too loose water
will leak around the ball. You can play with the ones in the boat supply store to see how they work. it will sometimes take a lot of energy to initially loosen the two parts
. Which is why you play with them in the store first.
- - Back on you boat try turning the shut-off/on handle - but be careful, if they have not been "exercised" in many years the handle will be too difficult to move. Which is why it is important to do it while out of the water
. The handle will start to bend if the ball valve is "stuck." Don't break off the handle. If the ball valve will not rotate, then using the knowledge obtained in the boat supply store, loosen the two parts
a little until you can rotate the handle easily. You can get some waterproof grease and with the ball valve shut off and a long brush paint some of the grease on the "ball" from outside looking up into the thru-hull. If that is not possible then remove the hose and unscrew the whole seacock from the thru-hull fitting and take it apart and apply new grease to the ball.
- - If the seacocks are white plastic try to identify exactly what brand they are. PVC or withe vinyl seacocks should not be used below the waterline. Marelon is fiberglass
in strong resin and are rated acceptable for use below the waterline. Usually they are always black. Replace any PVC or vinyl seacocks with Marelon.
