Ricco hasn't yet told the make of his starter motor. At £150 it won't be a Genuine Nippon |

Stayed out the night so I'm only just back on this. Plenty to check, thanks for all the advice. If it does turn out to be the ring gear would I be right in thinking that that's part of the flywheel so engine out, new flywheel, massive expense? (Vetus)

It could be bolted onto the flywheel but its probably quite a complicated job to replace it.
I don't think that's what is wrong but it could be.
I reckon the wire to the ignition switch is too thin. I didn't know about the thing @gazza explained where it draws too much current and destroys the contacts on the solenoid but that makes sense. I thought it was just that the power couldn't get through the wire. Similar principle really.
Is it all the original wiring loom or has it perhaps been modified or extended at some stage. And is the ignition switch original vetus supplied or something else.

The engine was rested overnight went to start it a few minutes ago. No clicking or clunking, the starter engaged and it fired up straight away. I switched it off and on a total of 10 times, each time it behaved perfectly. I'm not so naïve as to think that these things solve themselves, what might we make of this?

So exposed wiring somewhere maybe? |

Ghosts. Obviously. Or something to do with Brexit.
You already have some advice from TB on checking wiring, and Stabby's troubleshooting put-the-screwdriver-across-the-contacts-to-bypass-the-solenoid trick. So get checking and get testing. And read up on starter motors from t'Internet. I've always believed them to be dead easy to remove and put back. Just looked through our boat papers, apparently the 'faulty' starter motor was removed and a 'new' one put in Jan 2013; I have never looked at it to see if there's a make/model printed on it, so that's another little job for Christmas.
I like this video, but I'm a bit too thick to take it all in first go:

Worms. Or possibly maggots. For your safety I really hope its the latter.

So exposed wiring somewhere maybe? Hmm I gave the battery terminals, the isolator terminal and the solenoid connection a quick blast of wd40 when I was having the problem. Maybe that's got rid of the damp, suggesting a better clean up of the electrical connections is the best starting point, does that make sense? |

That your earlier checks on the electrics and connections weren't exhaustive or thorough enough ! The fact that the starter motor has worked faultlessly following an overnight period when none of the onboard electrics were subjected to any use suggests that there is some current drain from the starter battery when the auxiliary/domestic batteries are in use. Do a thorough check on the entire electrical system, beginning at the batteries and checking voltage at and either side of ALL connections and components on both engine starting/charging and auxiliary/domestic circuits, and paying particular attention to whatever you've got, or should have, to isolate both systems from each other. |

Yes have to admit my clean up of the connections was a bit cursory. The next dry day we get, a proper job will be done!

One other possibility:- A crappy cheap red key battery isolator while give similar symptoms- you can rule that out bypassing the isolator by putting both cables onto one stud, if the problem stops get a decent isolator to replace the problem one. I have these. Could I please have some recommendations for replacements, I have seen people not impressed with the rotary multi position isolators (Off,1,2,both). |

I have these. Could I please have some recommendations for replacements, I have seen people not impressed with the rotary multi position isolators (Off,1,2,both). Blue sea systems is good but pricey. www.bluesea.com/Ive ditched the red key isolators, we have one good quality off,1,2,both isolator -its make before break and has nice thick contacts with a good amount of spring tension on them, I’ve stripped and cleaned the contacts once, it didn’t really need it as the action of rotating the isolator makes it pretty much self cleaning anyway. It was pointless having a couple more connections in the system to Isolate the already isolated circuits. A red key isolator let us down after a two hour run - shut the engine down in the afternoon when we arrived at Oundle cruising club, went to leave the next afternoon and no go - strange! A bit of investigation revealed the red key isolator to be at fault, out with the spanner’s and cut the useless piece of crap out by putting both cables on one stud. Turn the key and we have ignition  that was the last time it was ever used, when I did a refit of the cockpit the wiring was rejigged and the crappy isolator hurled in the bin. the red key isolators fail because of cheap flimsy construction- the sprin pressure on the contact fails, the keys fail, they are generally nasty unless you spend good money on them. |

If it does turn out to be the ring gear would I be right in thinking that that's part of the flywheel so engine out, new flywheel, massive expense? (Vetus) Ring gear is box and flywheel off, sweat ring gear off flywheel and shrink it back on in a new position so the starter works on an unused part of the ring gear, no cost in parts but plenty of effort. i think you have a Hurth 50, nice and light, bit easier than mauling about a 50 odd kilo BorgWarner velvet drive in the depths of the engine hole. All academic anyway as it sounds exactly like it’s piss poor wiring/connections/switch gear that is causing your woes |

BANG IT WITH A HAMMER AND TELL IT WHO'S BOSS! hee hee hee .... you should have heard the apoplexy on the other side when I suggested this (I actually said try giving it a sharp rap to get it running as a temporary measure to get him home) They raved and waffled on about how could I suggest that, if it was a modern starter it would shatter it's internals etc etc etc Dorks !!! If they read the posts from the start, he had posted the make of engine which meant it was an old style starter |
