Broken Marine Engine Heat Exchanger - How we 'Unbroke' it!

I'd been asked to repair a badly corroded heat exchanger from a small marine engine.
This involved machining some new parts, then a trip to Maximus Ironthumper's workshop for a bit of blasting, spraying and burger eating before heading down to the boatyard in Plymouth for fitting and testing.
No vessels were sunk in the making of this video!

Good stuff! Nice to see it back in the water and chugging along, top marks all round.

@spungletrumpet 3 года назад

Yes, the skipper is very pleased to have her back in the water again. Thanks for your help, as always! I think I've got enough footage for an ironthumper instructional paintspraying video at some point as well!

I love it, Peter Wrights Spy Catcher and a curry takeaway box folded into a "how to" video. lol. My kind of man cave.

@spungletrumpet 3 года назад

The curry container contains one of my Daughter's 'experiments' involving melted candle wax and brass wire. I have no idea what it's supposed to be! There's a lot of stuff like that round here! ;)

@pyrrhical3423 3 года назад

As soon as you said Plymouth, my ears perked up as I live here. Then at 20:00 my old boat shows up!! Didn’t know she is kept there! I sold her last year so this must be millbrook? It’s the blue 19ft caprice. I do miss the boat.. just not the wallet damage !

@spungletrumpet 3 года назад

Ha! Small World! Yes, the boat I was working on was in Millbrook. They are a great bunch of guys there and it's always an interesting place to launch from. Gipsy Moth III was in the yard at the same time I was down there and launched the same week as we did. Really wish I had more time to spend actually crewing, rather than working on boats out on the hard standing!

@ASCIITerminal 3 года назад

Regarding the price of spares, anybody who has been around boats for any length of time knows that "boat" is actually an acronym for "bung out another thousand". Those Beta Marine engines are pretty fair (marinised Kubota from memory) but Max's Lister will probably last longer!

@spungletrumpet 3 года назад

Yes, they are a Kubota with a few bits added. I quite like the Beta engines, and the newer ones seem to have completely solved the little issues that this particular engine had. May Father always warned me about sailing that it was "Akin to standing fully clothed under a cold shower tearing up twenty pound notes." I always like to think that anything I can do to help extend the life of components as much as possible helps to mitigate that slightly for the owner! ;)

@richarddavies-scourfield8413 9 месяцев назад

Just seen this great video. I MAY have a similar problem. Why not make the rings from a suitable plastic. Then the bronze is insulated from the alloy and the ring will not corrode?

@aidanscapeing 3 года назад

Well done

@Simon78 3 года назад

@Hambini would’ve had a fit at the factory alignment of those end pieces! Nice work getting that cleaned and sealed.

@spungletrumpet 3 года назад

It's an odd design. The bits that had corroded are only really there to hold the O-rings between the tube stack and the end caps in place so it doesn't matter too much if they aren't straight. The end caps aren't even designed to be a tight fit! It does seem a bit shoddy though.

So what was the next job? I've just gotta know, now. Being in Plymouth, you were very nearly in the best part of the UK. CORNWALL- Buddha's own country.

@spungletrumpet 3 года назад

Well, the boat was launched from Torpoint so we were actually in Buddha's own country, even if only just! The next job was 250 miles away in West Wales, working on a little off-grid cottage in the mountains. Unfortunately it's not something I'm allowed to put on RU-vid - but maybe one day!

@chriswills9530 3 года назад

@@spungletrumpet Thank you, I can rest easy now. I kind of hope you were converting the cottage to a huge, multi-pipe organ, but I suspect it was a much more practical and useful job, that we would all admire equally.

@bobbod8069 3 года назад

Putting your finger in and tasting it, isn't a good enough test to see if there's any salt in there. In order to follow best engineering practice, the correct test is to make a cup of tea with the water and see what it tastes like. A dipped Hobnob can be used as a secondary test. Other than that, welldone.

@spungletrumpet 3 года назад

I tend to use the 'taste test' for battery acid too. Which has been known to raise a few eyebrows!

@edgeeffect 3 года назад

As a representative of the safety police... I'm glad to see the tasting was done before the addition of anti freeze.... if only our stupid cat could grasp this simple rule.

"If I talk enough, you'll just get frustrated and do it".... sound like a good methodology to me! Watching American RU-vid channels I've often thought about what "we" use instead of JBWeld.... seems the answer is... um... JBWeld.

It does seem that JBWeld is ubiquitous in the 'bodging cooling systems' world.

We have a few beta engines in our work boats and I do rate them. We did have the same sort of problem with a large build up of corrosion, I asked Beta who we have a good relationship with on a good price for a new heat exchanger and I nearly fell over!! I ended up having the engineers at Bristol Port do a quick repair as the engine wasn’t it great condition , a year later I put a beta 30 in which is running fine… anyway, good fix and nice sailing boat, it looked like a Cobra 750?

@spungletrumpet 3 года назад

Cheers! Yes, this one is a Cobra 750. It's surprising how many of them still seem to be about. I've been provisionally booked to change the saildrive seals next year (as the insurance company insists on it). That is always a nightmare of a job.
