Hi all I have just got my first yacht 
I know nothing about sailing or old diesel engines.
My boat came with this IMG_0393.jpeg
So this is i take it the heat exchanger ? So the raw water comes in cools the engine and goes out the back. Things i need to know, Is this serviceable ?
I will be replacing all hoses and hoseclips ( With stainless ones )
What is the corroded t piece ? there is a wire coming from it could this be temp sensor ?
All help on this would be much appreciated

I have removed this from the boat. There is no way of opening it. Seems to have been welded at the end.
So all i can do is flush it out with fresh water. is there anything else i can flush it out with ??? Broax ??
What will keep the salt at bay ??????

They are not serviceable parts, all you can do is flush it but to be honest I never take heat exchangers off unless there is a problem. More important is to find the engines anode and replace it, lots don't and the resulting calvanic action is more of a problem than salt water corrosion

Hi Bert
I have read a few of your posts glad to see there at least 3 of us with Halcyon 23s
I will have a look tomorrow for the anode. I have a petter ac2w nice old engine im looking forward to give her a full service.
If i hadnt taken the exchanger out i wouldnt have found the rot but heyho.
What engine do you have ? Is there anything else to look out for ???
Im a total novice on sail boats but i can deal with all the electrics Glassing and Joinery 
This is a project that i will try and share with this forum 
All info/advice is very much appreciated

I did have a old Volvo with the boat, replaced it with a 10hp yanmar raw water cooled so no problem with heat exchanger and gives me loads of room to work on it, I still got loads of refurb to do. This winter will be spent on new rubbing strake and interior work mainly,

Yeah thats my plan over the winter inside and all the external wood work. For the woodwork i have been using Oxalic Acid it has brought the wood out like new again. i have not oiled or varnished yet just bleached out all the mould and black water stains. I intend to using on the rubbing strake no need to take it off just use it in situ.

Look foward to see how your interior work goes.
Do you have any pics of how she is just now ?
During the week i got down to the harbour for a few hours and managed to the toilet out but then found rot both wet and dry all along the starboard berth bottoms all the way back to the starboard locker [frown] so its fiberglassing this week heyho
the joys of a 50 year old boat
