Hi to all.
I have a Santana28 with a Bukh DV10ME. I've had the boat twelve months and not knowing its history I don't why what's happening is happening. The engine ran very hot with the alarm sounding all too often, in an effort to increase the water flow I removed the thermostat. this had the desired effect, however, when I tried to inspect the pencil anode the plug came out and left the anode in, someone suggested I just knock the anode into the water jacket where it will dissolve and replace it with a fresh one. I tried to knock it with a screwdriver and a hammer but it really didn't want budge, so I left it alone. On asking a few questions It was suggested that the cause was salt build up in the water jacket and I should drain the salt water out and fill the system with a mixture of vinegar and fresh water and leave it for a week. Has anyone experience of this method or is there something else I can do. The anode has been in for twelve months and I'm wondering if any cooling water is getting to it at all, maybe it's so encrusted that it's not doing its job. Any help on the subject will be most welcome. Max.
