I have a 1995 Hunter 40.5 and a leaky connection where the shower snakelike hose coupling attaches under the sink--its the small rubber washer that is the culprit so the leak is behind the coupling. I am having trouble finding a suitable replacement washer--I have gone ahead and used some marine clear sealant and will know next time I go down to the boat whether or not it works. Meanwhile looking for a replacement washer.
