2004 305 Conquest suggestion for replacing seacock valves

During this winter I was doing some clean up on the boat and turned the livewell/raw washdown seacock to exersise it and the handle broke right down to the stem. Fortunately it broke in the closed postion. The valves are some sort of plastic. There are four seacocks all made of plastic. I was surprised. Each of them seem really flimsy. I was thinking about replacing the three 3/4' ones (size ?) with brass. I'm going to leave the macerator one alone. Would any old brass valve of similar size do? I found some at Home Depot that look like they'd work well. I'm not near my boat at the moment. I don't remember the diameter of the through hull fitting the valve screws onto. Does anyone out there know? Does anyone have any suggestions? Should I just go to the BW dealer and buy a replacement plactic valve? thanks in advance Stratocaster stratocaster attached the following image: [68.32Kb] Edited by stratocaster on 03/20/09 - 10:54 AM

The BW part number is 0557959. You could probabaly do it youself, but I imagine you would need the boat out of the water.

I have exercised my seacocks in the past but don't remember them being so flimsy. I wonder if BW is using different valves? I'll keep you posted of what I see on mine. Let us know how you make out.

I had my hands full this weekend with general cleaning and compounding/waxing. I stopped by the Whaler dealer in my area and was telling him the story of me working the livewell seacock and before I could finish he was telling me that I broke the handle off. He said it happens alot. He suggested opening and closing them at least once a month. The more the better. I showed him my home depot 3/4' brass valve he said it should work fine. My only concern is the handle will rust. I'll post a pic of it when I get a chance. thanks stratocaster

As it turns out I decided to go with the West Marine forespar plastic replacement valve that jollyrog305 suggested. Thanks Jollyrog305! I came to the realization that the plastic replacement is actually a good idea since it won't corrode and it's not conductive. Like any valve you need to maintain them. While I was replacing the livewell seacock I checked all the other valves. I noticed the air conditioning seacock was sticking pretty bad. I took it off and greased it and it's fine now. thanks again! Stratocaster

Fortunately the valve comes apart at the bottom and I was able grease it up. See pic below. stratocaster attached the following image: [7.78Kb]
