What I find difficult to understand with the corrosion is why its gone so quickly. I've got a 35 year old quintrex that I never wash and had lots of salt water in it but its still going strong. I even discovered that its got a neg current in it from the motor. Was the alloy better in those days or is there something else happening?
People would want their well made plate boats lasting longer that 12 to 15 years as with the two examples mentioned here.
