Hi, my nephew has a badly corroded heat exchanger tank, does anyone know of a good source to get one avoiding main dealer prices at all ? Any help appreciated.
Nanni N2.14 2004 heat exchanger

Highly unlikely - it is a Nanni exclusive part - just like most other marine engines there days.

What do you mean by 'heat exchanger tank'? I've just assisted in doing a replacement engine.I don't know what the owner is doing with the old one,but I will see him later today.
Cheers.

Good morning and thank you both for your replies, it's sometimes called a header tank I believe but where you put the coolant in and there is a rack if cooling pipes to help cool the engine.... I'll see if I can find a picture...
Thanks

Hi.The header tank is at the top of the engine ,and is the point where you would add' coolant'. The heat exchanger is where salt water cools the 'coolant', and holds what looks like a handfull of straws glued together.This is mounted on the port side of the engine above the starter.
On 'my' one,the header tank is ok,but the heat exchanger has rotted out through lack of winterisation.
Hope this helps.

In the operators manual,The Heat Exchanger is item 9. The 'Recovery'tank(I refered to it as a header tank) is item 12 in the pics.

On checking,I am incorrect here.You would add coolant at item 10 'Coolant Filling Plug'. Sorry about that.

That is the heat exchanger, and it will be expensive as it is unique to that model (both 10 and 14hp versions). no practical alternative, although depending on where the corrosion is, it may be repairable.

Thank you both, been helping trying to get it off, not sure if its repairable due to the fact its cast alli, think the best bet might be checking engine breakers as already mentioned its eye wateringly expensive. I have the 10 hp in my boat and very pleased with it but probably like most of us prey nothing big goes bang although I do all the maintenance at the stated intervals. Thanks for all the help much appreciated

I had this a few years ago. I couldn't lay my hands on anything other than a new one from Peachmont. However I had to get a man in to remove the old heat exchanger. He ended up using a screwdriver and hammer to get the last nut off. It's impossible to get a spanner or socket in.

Yep funny you should say that ... not a great piece of engineering that.... think we may have to bite the bullet but will look around first.
Many thanks
Many thanks
