[C320-list] Water heater not getting as hot from the engine

[John Morrison]

I eventually got rid of the lock buy running the engine for short periods, a minute or so, and then adding antifreeze to the engine. It took about 4 times before the antifreeze would circulate properly. I also made sure the antifreeze surge tank was properly topped up. 
By the way I’ve now replaced most of the hosing. I’ve just completed replacing the anti-siphon hoses on the engine running to the port lazerette. There are two of them each 10’ long. On lift out I’m replacing the hose on the chain locker drain.
