I don't have that problem yet, but I wonder if it is a problem with a washer within the valve. I have not needed to take apart a boat faucet, but a home faucet has washers and o-rings within the valve assembly that can go bad. Yours may be defective or not installed correctly.Update - I replaced the aerator, which is what screws onto the faucet (washer within the aerator). It now allows a much better flow of water, but still a nasty little drip.
