Yeah big thanks to Wheels and to Ashton. Ashton also wins the prize for diagnosing a dicey deck switch for the anchor winch. Thanks again for your company Ashton; I owe you one.

Thanks wheels. It sounds like the solenoid set up isn't working. The lever feels very sticky. I'll try to get it working freely. I'm gonna kick myself if this whole saga is a broken spring on a solenoid. Grrrr. But just to get it clear on my head, when the black button is released, the spring should pull the lever back?
-
At idle it ran smooth enough but blew a bit of smoke at high load. I'm not sure where the stop lever is, but to shut down I press and hold a little black button on the ignition panel for a couple of seconds. I don't actually know how the little black button works. When I first got it started on Sun 27 March it conked out under load but started immediately when I turned the ignition again. Perhaps the gold lever with the boot on it is the culprit when I moved it back and forth it was a bit sticky. Would it run fine for over half an hour if there was a fuel/air problem but fail to start seconds after shutdown?

UPDATE
I got the engine started again yesterday (had to use ether and pump the little blue lever). I ran it under load for 30 mins. Then I thought I'd turn it off and try to start again. It wouldn't start normally. So now I suspect it might be the glow plugs. Do I need a special plug socket spanner to remove them? Any more tips would be welcome.

I am in the fortunate position that I am the conn-ee, Mrs Aardvark is the conn-er.
In such situations she just giggles, throws more canvas up, and leaves me to it while I wallow in the bilges fixing stuff with gaffer tape and paperclips, swearing loudly. Its about the only sailory thing I can do.
If you haven't been taught the joy of heaving-to and the incredible dramatic change it brings you have indeed been conned. I make it a condition of boarding that my conn-ees know how to heave to. I just noticed it's number 2 on my list. I should make it number one because of how useful it can be in an emergency. https://kmccready.wordpress.com/2015/01/05/storm-fantasy-sailing-yacht-safety-card/

from experience, when you are dead in the water 300m off the river entrance at Clevedon in a howling NE gale on a rising tide...
Did you suddenly have fuel problems and have to fix it?

When do you actually use the pump primer other than resetting after new filters? Maybe it was my pushing it a few times rather than the ether which did the job. Sorry to my mentors if I just failed the Diesel 101 test.

Thanks for the warning on the bug. What biocide did you use?
-
I'm ready for the test now. Thanks to you guys I might just scrape through. Heaps of thanks again!! I'm still whooping for joy from when the engine started.

I've been down a rabbit hole for a while learning about banjo bolts and double banjo bolts which I'd never heard of. But I can't figure out which fuel line or lines we're talking about.

Thanks Ashton! So it seems the guy who sold me the fuel filter might have been right after all. He said just whack it in after you've filled it with fuel and shouldn't need to bleed. I'll take the black box back to him and ask. But I couldn't see how you could get a filter into it. Maybe the whole plastic shebang needs to be replaced.
I also discovered that the solar panel seems to only keep the starter battery topped up. The house things came back to life after the engine ran for a bit. I'll have to chase it up.

Success! Thanks. I want to thank each and every one of you.
Here's what I did with my wife's help. And some interesting things happened.
1. drained about 50 mls fluid from the primary filter and it seemed to be diesel
2. loosed the blue bolt on top of the secondary filter and cranked it and then tightened again (didn't see any bubbles)
3. Took off the black plastic box (which I think is the air intake but I'm not sure). Pic attached - the black box came off where the two bronze looking large hose clips are at the bottom left of the pic. Strangely the box seemed to be empty. Is it meant to have a filter in it?
4. Sprayed ether mix (Start Ya Bastard) into the hole for 2 or 3 seconds and tried to start
5. It ran for a few strokes and stopped. Repeated 4 about 5 times and each time it ran for a few strokes and stopped. So I pulled the bar on a spring a few times with the rubber concertina boot secured by the silver keyring thing. I thought it might be the manual fuel pump, but perhaps the manual fuel pump is the little blue leaf-like thing so I pressed that up and down a couple of times too; it's at the very bottom right of the picture with the keyring.
6. It STARTED and ran for three minutes and then slowed down - my wife and I both heard it and thought - uh oh.
7. I put the revs up in neutral for 10 mins
8. Put it into forward and it didn't like it - slowing down to almost stall
9. Put it into reverse and it clunked to a stop.
10. Oh god I thought, the propeller or drive shaft has seized.
11. started again without ether. started first time
12. Ran it at high revs in neutral for a minute
13. put it into forward again and it slowed but didn't stop. I let it labour a bit and then into reverse and it didn't stall but slowed to almost stalling
14. repeated 13 a few times
15. Then (perhaps 15 minutes after start up) it went into gear without complaining
16. Run it hard in gear for a minute and heaps of smoke came out for a bit and then smoke stopped. I ran it under moderate load for a few minutes in reverse without problems.
So I'm guessing there was some sort of blockage stopping it from accepting the load of the propellor. Maybe it had water stuck inside as someone warned.
I couldn't find the governor screw.

I'm just about to leave. Before I do, what does it mean to say the governor might have a release screw. What's the governor?
-
Once again, thanks heaps. You guys are amazing. I'm keen to get back out there and have a go now. I'll let you know how it goes.
-
If it's a water trap. How can I check there's not too much water? Or what happens to the water which is trapped?
-
Wow. Thanks for that. I thought I traced the second one (the one close to the engine block) back to the fuel tank. But I could be wrong. My friend said a return was common but he's no great expert.
Yes they need replacing.
How should I check that fuel is getting through?
My friend said it might be the injectors too.

The engine cranks but won't start. It happened rather suddenly. It's a Nanni 15, 2 cylinder 2-60he
Does anyone know if the glow plugs run off the starter battery or off the house battery. I'm not on the boat now and didn't think about that until I got back to shore. A friend helped me spray ether into the air inlet but that didn't help the firing.
I thought I'd replace the fuel filters to see if that helps, but I could be on the wrong track.
We just discovered there are two fuel filters, one on the intake side and one on the overflow to take fuel back to the tank. But the intake one (see picture) appears to have a screw on glass at the bottom. I haven't fiddled with it because I want to know what I should do first.
Any tips would be appreciated both on the failure to start and on the fuel filters.
Would diesel bug cause these problems?

Nice. Good to see at least a couple of PFDs worn too.
I clicked on the next link too about the appalling behaviour of OneSails blaming a fraudulent sail loft in South Africa for ripping off Jason and Nikki Wynn. Seems to me that if you're a global brand you need to have systems in place in case your licensees turn out to be arseholes

Quick, drop the anchor.

Just on a point of law, and correct me if I'm wrong, but my understanding was that evidence in recordings can be submitted and heard. But as always, it's a case of how much weight, if any, the court gives to the evidence.

From my point of view it's fine to discuss. But more info would be needed. Pictures and why you think the yard is responsible. NZ has a cheap to access Disputes Tribunal if you can't come to an agreement. https://disputestribunal.govt.nz/how-to-make-a-claim/apply-online/
