Antifreeze for Raw water circuit Volvo Tamd61 (Fairline Sedan 36)

[sharpness]

Reading few threads regarding winterising got me thinking, although i know the volume of coolant for fresh water circuit on my Volvo Tamd 61 (30 litres), i don't know what the volume is for the raw water circuit, engines are fitted to Fairline 36 Sedan.
I would like to know in preparation for when i pour 50/50 antifreeze mix through water strainers for winterisation. Unable to use the method of when it exits exhaust the circuit is protected, as the exhausts exit underwater.

If I were to guess, then 8 litres per engine of 50/50 mix should suffice, but if anyone knows the correct answer I would be very grateful.

Raw water drains.

There should be drain points to get rid of all the raw water in the galleries, check the manual. There was on my Mitsubishi (Thornycroft clone) & Yanmar.

My old 63Ps took 25 litres of mix to get antifreeze mix at the inboard silencers. If you can't see the exhaust, you could disconnect the small cooling hose from the reverse gear cooler to the exhaust elbow, at the exhaust elbow, and aim it away from engine/electrics etc. You will only need to run the engine for @ 30 secs so the exhaust will be OK. Then you would know for next year exactly how much was needed.

On the winterising theme - did anyone else read the feature in MBY with the poor chap whose engine froze in his Humber 40. Cost a fortune to rectify.

Thanks Kashurst. Assuming that 25 litres was per engine. If so looks like my initial guess of 8 litres per engine was a bit out. Must confess my guess of 8 litres for TAMD61 came from viewing the MBM youtube clip, where neale winterises the raw circuit on a Turbo 36 which is fitted with Volvo TAMD60 and he quoted 6 litres of antifreeze mix was needed for raw circuit per engine.

Hi Sharpness.

If i was asked to winterise these engines I would first make sure the heat exchangers and aftercoolers were drained of water first. The reason for this is two fold.
1. Gives you an opportunity to check the state of the drain bungs/plugs.
2. Ensures you winterisation mix is not diluted by the water present in the coolers.
I would also drain the exhaust silencers for the same reason if they have drains on them. And if you leave the drains open you will see when you have put enough mix through them. If there are no drains then 25ltrs of mix per engine would cover you for the engine and the silencers. Better safe than sorry.

Regards

I read the h40 report.

In 1995 my father was going to buy perche no, it was in Barcelona , he could have bought it then for 60k, when other were for sale her at twice that, it was in a he'll of a state then at it had been left and was a repo I'm told, it needed a new gearbox before it could move and the interior was in a mess, hence he didn't bother even a that price. I doubt the last engine problem was temp related, more like a problem built up over years of neglect.

Anyone remember cape yachting ? The Hateras dealer in shamrock quay, they were the agent for it way back.

I did enjoy reading the story as my late dad was my best mate too, we did lots together looking at boats and buying together, kind of miss that. I'm glad to see someone got some use out of it, I've always loved Fred bookers boats, he was a house builder who loved boats that much he decided to build them for himself. Reading the story bought back many memories. I'll write a report one day of when we went to Majorca to buy a histar 42, it turned out to have a real celeb first owner.

Hi,

How would you fill the freshwater system to ensure you keep the impeller wet?

Thanks
