Calling all Yanmar/Diesel engine enthusiasts

When dealing with hoses I've found that putting the end of the hose into a jug of boiling water will often soften it enough to get it onto the elbow. Has to be done quite quickly as the hose cools and goes hard again. You need to let the hose get hot all the way through, so three or four minutes in the water is needed. Wear gloves......

I do that and put plenty of silicon grease on the the metal elbow. Hot rubber + slippery spigot usually does the trick!

Thanks chaps! I'll try the boiling water trick - LOTS of swearing yesterday (what with that and trying to do my gas fit out under my makeshift cockpit tent in the driving, horizontal rain :beaten

Vyv,
Are these thermostats interchangeable? Much as I like the lads at Bukh their thermostats are horribly expensive so a cheaper alternative is a nice idea.

From memory they are not but it's a long time since I have seen a Bukh one, and never seen the two side by side, so I could be wrong. Photo of one here http://www.boatpartsandspares.co.uk/bukh-dv10-dv20-thermostat-1812-p.asp

Apologies for reviving this thread, but now that the boat's out for the Winter I thought I might use up the Rydlime that I have from the last de-scale. The engine is a Yanmar 1GM 10.

Having read through the above posts it all seems quite straightforward. However, the latest edition of PBO details the cleaning of a Yanmar 2GM, and suggests the fluid should be pumped through, using a 12 volt pump, " I ran the solution for two hours one way... then reversed the circuit and ran it for hours back the other way". Is it really necessary to pump it through like this? When I did it previously I just removed the thermostat and gently poured the solution into the system (much fizzing!!).

This time I intend to use a bucket with the solution in it and run the engine as Rob F post 37 suggests, without thermostat, and circulate the solution back to the bucket, then leave it in the system for a few hours, then flush it out. I will also leave the engine anode in place as to remove it requires removal of the alternator. The anode is to be replaced anyway this winter, so I don't care if it's eaten, LOL! Also, the water pump impellor will be replaced at the start of the new season, after the antifouling is flushed out. Which brings me to another question. Is it better to use the Rydlime first, then leave the antifouling in over the winter, or use the Rydlime after the antifreeze is flushed out? Does it matter which way?

Thanks for any suggestions

Geoff

Question 5. Clean up the spigots with sandpaper to get a smooth surface. You may need to replace the rubber pipes if the ends are stretched or split.
