I'd rather my engine stop than take £1000 of damage....oh and stop at the same time for any reason.
Dunno why it stopped, but the battery terminals coming off can't be blamed on the engine. What usually happens is that the terminals work loose & you get continual arcing, this would play havoc with any electricals, let alone be a fire risk

Huge difference in torque .. as PD alluded .. think about it .. two fingers on a large nut against a 6 inch spanner in the same hand .. no contest

You can nip a wing nut up with fingers, screw driver, spanner, bit of a shackle, almost anything, can't do that with a nut

I'm not trying to argue with you, I've thought about what's been posted on this thread and I still can't understand this wing nut thing, if I was out on the water and somehow in the shit with batteries I would much rather have a wing nut that I could take off with a knife or anything I could jam between the wing and the thread than look for a specific spanner, you can't put a load of torque on the nut anyway because of what they are made of.
Your right though about arguing, it's too hot and I've only had 2 cuppa's

Don't know why it stopped,but stopped it did we thought at first that it was a fuel problem because the engine spluttered and died then when we tried to raise the leg we realised that we had no electrical power.Could it have been the
fuel pump,does that need power? any way as soon as we connected the booster we were off and running,we didn't realise at the time that we had no charging facility

It sounds like the charging circuit went early on, possibly on the previous outing even, which means you lost the 12v output from the emm, this supplies the high pressure fuel pump & the other 12v systems & charges the battery. The systems would have been running off the battery until it either a, went flat or b, the terminal came off, at that point you lost fuel pressure. Considering the conditions that day, you probably hit a wave & the bump was the final straw & the terminal let go. Etecs WILL run without a battery but only if the 12v output from the EMM is intact, which in this case it wasn't. Running without a battery is a bit of a moot point imho, because you have to start it without the battery, you can't start it on battery & then disconnect it, as it nukes the EMM, as you know There is a video somewhere of someone pull starting a 150, but I wouldn't want to try it on a 250 big block

No, the etec is the only current engine which needs no battery once started.
