1982 CD Cutter raw water seacock showing a drip every two seconds from area of locknut. Does this necessarily mean replacement or can regreasing resolve the problem? Only the 2nd season of ownership and do not know when seacocks were last serviced. Also any tips on how to best complete the service.
Many thanks,

Had the same problem recently...just tightened the clamp on the hose and problem solved....try this first before tackling the seacock. Also, you should take apart your seacocks and regrease them this fall...that way you will know when there were last done. Most folks on this board will tell you to take them apart annually, but I have found semi-annually to work fine for me.

Re: Raw water engine seacock leaking.
Jack,
This is not necessarily a problem with the seacock.
1. If the seacock can be presently easily turned, it may be loose. In which case the locknut can be loosen just a bit to take the tension off the washer and adjustment nut which is under the locknut. Then tighten the adjustment nut to a point where the operation of the valve handle requires a firm but not a hard force to operate it and note the leak rate. If the leak stops, then just tighten the locknut against the adjustment nut and you are done.
2. If the seacock is already very hard to turn, then the best way to handle it is to pull the seacock apart after the boat is pulled and lap the valve barrel to the valve body with lapping compound. You can note any deep scratches, etc. on the mating surfaces to determine if lapping compound will work. Clean out the lapping compound and grease before reassembly.

Re: Raw water engine seacock leaking.
Jack,
Ditto the previous comments, however you don't have to wait till your next haulout to fix the seacock.
On LaVaida we have wooden plugs tied to each seacock in case a hose or other problems occur. You can easily remove the seacock (careful not to damage the threads) and install the plug in its place. If done quickly very little water will get into the boat.
A note here....most folks have no idea of how much water can enter a hull through such a small hole. Its a good demonstration of the reason you have a plug tied to each seacock.
LaVida has been cruising for the past 26 months and I regrease my seacocks about every six months or so. Nothing worse that a sticky sea cock.

Re: Raw water engine seacock leaking.
I had the same problem with my seacock recently after only a year. Seems the only grease to use is the Moreys red. I had used the white stuff. The intake on my engine seacock has a basket type screen on the outside and I wanted to hone lap the barrel and plug so using the wood plug from the inside was not an option. I have used the foam noodles with success on the other thru hulls but here the screen prevented that. I bought a small sink plunger at Home Depot and drilled a L screw into the center. A little vasoline on the lips of the plunger helps the seal. I then went diving hooking the L screw into the center hole of the screen and thereby placing the plunger over the entire screen intake. This staunched the water flow to a managable dribble. I suggest however you have a good working bilge pump in place since the amount of water coming in is still significant. If the water gets ahead...just put the plug in the barrel and take a break.. till the pump catches up.
Lapping compound and Morey's red can be obtained from NAPA.
Saved a haul out charge on this one.
