Here in the Pacific NW (Vancouver) we're getting freezing weather now, which rarely happens. Many people keep a small ceramic heater running in their boats, but what if the shore power goes out?
Here is what I did last week to prep: 1. Run 2QM20 raw water cooled engine under load for 20min to warm it up. Stop engine. Close seacock. Open sea strainer. Start engine. Pour RV antifreeze into the sea strainer. Stop engine. Close sea strainer. 2. Drain fresh water holding tank system. Run RV antifreeze through the pump and faucet. 3. Put RV antifreeze in the head and pump into empty holding tank. Run macerator enough to get antifreeze in lines. 4. Put RV antifreeze in the bilge What do others do? Any tips? Thanks, Jeremy
