The continuing saga of the broken heat exchanger!!!!!

I wasn\'t trying to be rude ...

I was amazed that from 800~ we escalated to over 3K .....

I would recc'd a look in Boats and Outboards Mag ..... or in Boats for Sale .... you see plenty of second-hand engines for sale of all types ... and also parts. You could buy a complete Sole engine and have it as spares etc. - it may not be a good runner - but many parts will be good enough and save you a fortune.

I am not an engineer but would find a way to save spending out such amount, irrespective of selling boat or not ... in fact I think it even more reason to not spend out too much. Sorry but i do not agree that value of a boat goes up with having a new engine installed. It may make boat a better bet for a buyer - but he wont increase his offer so you get your money back ...

Seriously there are plenty of ways to sove this one .... the best is the second-hand engine for spares route ....
 
I seem to remember that you had a section of pipe split due to frost & that it was 15mm diam

Is it possible to cut out the old bit & leave enough each end to get a compression fitting on ?
i know you cannot put a straight bit between the 2 ends but you could manufacture a length with a loop in it then this may spring back in between the 2 ends.
I would use copper but lets face it the modern speedfit fittings & plastic pipe could do as they are made for high temperature & water under pressure boils at a higher temperature than at atmospheric temperature but not above speedfit limits.
If it were possible to cut the split bit out have you investigated whether the water runs through several pipes at once. If so you could cap the ends with compression plugs. To solder the split yourself is not that hard if you can get to it.
You need silver solder & flux which you can get from a tool shop. You need a good quality blowlamp with a limited flame spread such as the Rothenburger ones sold at travis Perkins etc. Silver solder melts at a much higher temperature than ordinary solder & with a bit of practice on a couple of lengths of copper you could do it. Get a book on silver soldering from the library. A lot of model engineering books cover the subject adequately
i would certainly not give up on repairs yourself.
You can pressure test it by filing with water and pumping up with a car pump & testing with a car pressure gauge. You just have to fix a short bit of pipe on the inlet with a car tyre valve set in with a jubilee clip
Give it another look if someone else can repair it then you can. It just needs lateral thinking. You cannot mess it up any more than it is already
Good luck
 
i dont know if you have sorted yourself out yet but a company called HMI based at tetbury are now the importers for sole engines, i was there a few weeks ago, and they have just started with these,they have a web site so you can get the phone number from there,hope this helps they are nice people and also are the importers for isuzu engines, they will look after you
 
Re: I am amazed - no gob-smacked !!

It often occurs to me that marine engine manufacturers dedicate their lives to making everything to marinise the engine fit as closely as possible, with the consequent difficulties changing belts etc.
ANY device that is able to cool your fresh water by means of a flow of salt water will do the job. Consider a header tank remotely mounted, then some sort of intercooler, eg an oil cooler with suitable connections to allow the intercooling process. None of it is rocket science.
 
minquiers - thanks

You may have just solved my problem, Tetbury is about 30 Minutes away.

If everything else fails I will box it up and bring it home, and take it up to them. I am sure they will offer a good service and replace only what is nessecary.

Thanks again.
 
...Just one little point... Seeing Dickie's are being as "professional" as they are, wouldn't be surprised if they charge you for another company to come and work on the engine.....
 
Yes - that was one of my concerns. I have asked Dickies for a full written report and estimate for the repair.

I am looking at getting the boat shipped back nearer home, I would then attempt to do the repairs myself, a 30 minute journey to get the tool is not so bad.


So the next question does anyone have any experience of boat transportation companies??? 27ft.
 
Near all marinas have a closed trade policy ...

Ideally it is to protect the trades within the marina ... but inevitably ends up being a money spinner for the marina usually.

As long as any person working on the boat items is not obviously "trade" .... ie Works van etc. displaying Co. name etc. - you can pass them off often as "friend" helping you. You sort out "friend" privately.
