I had the same the main problem is the sea water cooled refrigerators they circulate all the time through the sea chest and clog all the systems. This is a difficult problem which can be sold by the fresh water tank circulation for cooling the compressors if the refrigerators.

Does your sea chest look like this picture. I was in Gib and the hull was very clean with no scrapping required. But after just a few months this happened.
And it can migrate through the whole cooling system. I have started doing regular flushing with mild hydrochloric solution, similar to Barnacle buster.
Yes I was shocked how quickly it formed.”

The problem turned out to be the transmission oil cooler which was 3/4 blocked. The gurgling has stopped - I'm pretty sure this was the exhaust anti-syphon pipe sucking in air because of the upstream blockage.
Thanks for all the advice, really grateful.
Interestingly, now sea water can flow at full rate, when I rev the engine to over 2,000 to engage the alternator the sea chest alarm sounds, so at least I know that works! I'm hauling out next week and will give the sea chest inlet a thorough check and clean out.
