I replaced the 6" high Marelon thru hull under the sink on my '86 32-III. This is the route taken by the cockpit drains. Using a 90 degree schedule 40 pvc connector, the drain hose now lays flat. The manufacturer of the PVC confirmed that the bursting pressure of any plastic fitting is only about 7,000 lbs versus the ABYC requirement for 10,500. I still have second thoughts. Even though the opening is about 12" below water level and less likely to freeze, the small amount of water in the elbow will be exposed to freezing air temps in the boat. Bubblers and heaters depend on a constant souce of AC. I'm tempted to undo this project. Any thoughts? I have thick skin so let fly with any admonishments...
