My 2003 BF225 has 1500 hours on it. In 2011 I replaced the VST bowl because a corrosive pinhole was allowing seawater to enter the fuel side from the cooling jacket side. Now here it is 2018 and I am facing the same problem. My boating is in cold water of SE Alaska, and I'm thinking about eliminating this problem by bypassing the cooling jacket on the VST. Does anyone have experience with doing this?
