I own a Beneteau Oceanis 473 which was bought new in 2004 and am wondering if anyone has had a problem with seacocks deteriorating. As having to replace them due to corrosion, electrolysys or galvanic corrosion. We have a 4 cabin version with a total of 16 seacocks. And has anyone had to link all the valves with an earth wire to a common external anode ? Cheers, Mick
