Bottom is the raw water inlet side.
I'm amazed we didn't notice any overheating. No alarm or smoke.
Clean your heat exchanger stacks, boys and girls!

Probably worth pressure checking whilst it's off as well? Mine had a leak that I otherwise wouldn't have known about.

I've had mine look like that and also come out nearly clean.It's never the same.The safe thing is to have it out once a year or so.

Ariam came to us with no raw-water strainer, just relying on the slots in the saildrive leg to keep big stuff out. The amount of **** in the heat exchanger was impressive, there were even baby mussels growing in there, attached as if to a rock. Was it overheating? Who knows - it turns out that on our delivery trip we were motoring without any alarms or indicators working, which we didn't know at the time. (The rev counter had been installed by a moron, and was half full of rainwater. We knew we had no rev counter, which wasn't a problem, but we didn't realise that on new Volvo engines the electronic rev counter is also responsible for sounding alarms.)
Fortunately the engine seems to have survived the experience, and is now hale and healthy.

Good timing, I am having mine done whilst I am back in the UK because I thought the engine was hotter than usual when I had to motor back to Marmaris just over a week ago. Approaching the marina another boat was well behind us, but the started trying to overtake and get a berth before us, so I put the revs up a bit and the overheat alarm went off! I still got there ahead of the other boat as the alarm stopped once I dropped the revs.

My son joined us in Guernsey this week, his engine was running at 85C, he put in Rydlyme overnight, immediate drop to about 70C. The stuff really does work.

Rydlime looks good stuff but how do I use it in the salt water side of the cooling system? No instructions on the website. Do I just take the topp off the strainer and add it then open the seacock again? If it's a hoses off job I moght as well clean the heat exchanger stack the normal way.
