*WARNING, WARNING, WARNING*
If you are one of the thrifty types who think "marine rated" products are a bogus marketing ploy DO NOT stop reading here.
This is a photo of a one year old YELLOW BRASS Home Depot ball valve installed by the previous owner. When I asked this seasoned boating veteran why he used a ball valve from Home Depot he said; "it was only in a pinch while coming up the ICW but after it was installed I forgot to replace it with bronze one".
This "Home Depot" valve was in use for about 8 months, of total in water time, and the ball, inside the valve, is completely GONE, NOT THERE, CORRODED AWAY! This valve was literally weeks away from catastrophic failure of the boat sinking type.
*PLEASE DO NOT USE ANYTHING BUT MARINE BRONZE OR MARELON ON YOUR BOAT'S SEACOCKS OR THROUGH HULLS! BE SURE WHAT YOU ARE BUYING IS MARKED UL MARINE.
