The waste holding tank in my Island Packet PC-35 is showing some serious
corrosion at the discharge fitting. This is a welded aluminum tank of 30
gallons. All other tanks (also welded aluminum) seem in perfect shape. I
have two questions. 1) "What happened?" and 2) Does anyone have experience
replacing this tank in the Packet Cat - it looks like it might require a
chop saw to extract?
