I have a 375 and the marlon sink drain valve is always dripping water into the vessel from the valve handle "cap" or from the handle itself. The boat is only 2 years old and the valve is used every time we are on the boat.
Has anyone any ideas of how to stop the drip without slipping the boat and replacing the valve.

It sounds like you have the Marelon OEM valves, there's a little white thing in the middle of the handle base with a loop on it? You pull that out and there will be a screw in there. Very carefully tighten that screw, the drip will *probably* stop, the screw frequently comes loose, I've had that happen twice.
Be gentle, if you strip the threads of the screw or otherwise break the handle off, the ball will probably fall out and you will have an uncontrollable gusher that is coming from inside the valve and it is very difficult to plug. There a fair bit of discussion about these valves on this forum, the C34 forum and the internet sailing forums in general.
BTW, the little white thing is a plug that you can put in the thru hull from outside the hull which will close off the thru hull should you need to do so to work on it. The loop is to tie a string onto it so you can pull it out when you're done without having to go in the water.
Here's the link Bud mentioned:

Thanks, guys. I'll give it a go, very gingerly. Thanks for the tip about using the cap on the handle. I wondered why it was there. Thanks, too, for the link.
