I've just drowned a Yanmar 1GM10 - any advice?

It runs!

Rather fortunate. Took the alternator in to be checked as my multimeter is, (catch 22!) on the parent yacht, but since Yanmar have very wisely built the starter and relay box into the bell housing, they survived OK as, more remarkably, did the battery and switch panel (which was well rinsed and dried).

Oilchange time I think....

Re: Stalwarts

The DUKW's were almost a laugh-a-minute, if it wasn't so sad.

We were on an operation to capture some terrorists right on the border with Oman. We had 22 of 22 SAS on board, with an invisible barrier around there spot on the tank deck - where the 500 regular soldiers of the Royal Irish Guards did not intrude.

We landed all the army by DUKW and on landing the terrorists ran up the jebel. The SAS were put on the top of the hill by the helos - and the terrorists saw them and ran back down, to be captured by the army. 25 terrorists were brought back on board and loccked-up down in an empty magazine room. They were later taken to Salalah by SAS guards, and "given" to the old Sultan. Not much became of their later life.

As for the soldiers, they had to be airlifted back on board as most of the DUKW's had engine trouble or leaks, and were being towed back to the ship by various means, and any DUKW still able to drive itself.

Mind you, the Fearless didn't come off lightly. She got a complete steam plant failure through the ingress of jellyfish into the cooling system. So much for warships.

As I said, nothing to do with the original thread - but interest nonetheless with a nautical leaning.

Re: It runs!

A relatively happy ending.

Still, these things happen at sea. If they didn't, there would be no anecdotes to write about and be commented on.

Re: Stalwarts

Although Stalwarts were, I suppose, definable as boats, and therefore legit in this forum, they were actually best fun when wading not swimming. On any sort of bottom with a smidgin of grip you could get them well above 'hull speed' and create a bow wave that would be the envy of a supertanker!

For the benefit of anyone else in a similar pickle - be sure to check there is no water in the cylinder before cranking the engine. It could get in through the inlet or exhaust valve if they happened to be open while the engine was stopped. You will need to remove the injector to check for water inside. Obviously there was none in your case.

Forget WD40 it is sooo eighties. The best product on the market for this problem is T9 Boeshield.

Cleans protects and leaves less mess than WD40. Good Luck.

I am boating again ;-)

Re: Stalwarts

I know, I know, great fun! Thats why they developed the big plywood boards for the front of them, or the water used to come up the winscreen and into the top hatches!

Re: Stalwarts

Come to think of it, having the wheel in the middle of the 'cockpit' was a bit boat-like as well.

There was also something about the non-differential drive system which made them 'squirm' when driven on a straight road and which need continual correction, again a bit like the constant correction you make when sailing in waves. I remember being instructed to hit the kerb from time to time to 'unwind' the transmission!

 

[Mirelle]

single cyliner engine with decompressor

A single has a better than evens chance of coming to a stop with both valves closed, as was clearly the case with mine, but I turned the engine over by hand, pulling cautiously on the alternator belt, with the decompressor lifted, then spun it on the starter with the decompressor off, before dropping the decompressor and starting it.

A twin would, I fancy, be bound to have one valve open.

Re: Stalwarts

The wheels had no "ackerman" principle of steering and no slf centering "king pin inclination" built in, which made them a bit "squirmy". The hitting the kerb, was because all the wheels on one side were locked together, small differences in tyre diameter, caused the transmision on one side to "wind up", didn't happen when off road, but did on the road, caused massive damage to the "Tracta" joints in the wheel stations. (I've rebuilt literally hundreds) Each side was seperated by a "no spin diff" an early heavy duty limited slip diff. Like I said I was on the design/proving team, so I'm a bit of a stalwart anorak I suppose!

I cant add anything, but agree with all the remedys, apart from re-engining? wiith electric!!

Can only say what others are doing. Diesel/gas folks are re-powering with electric. Electric folks are not re-powering with diesel/gas...

unelectric

I suspect Mirelle would be happier re-engining with genuine steam (fed by seacoal) than anything by Mr. Watson-Amps.

Re: Stalwarts

Still been a fascinating thread to read tho'
thanks for brightening up my afternoon
ps good luck to mirelle.

...It was like that when i found it!

Re: I\'ve just drowned a Yanmar 1GM10 - any advice?

A good friend of mine did the same to a 3GM.
Took all the necessary precautions. Cleaned and washed all that he thought would need doing.

After that season wintered it as usual, fine? No!

The next season he had a loss of power that he couldn't trace. Eventually he had to go to the main dealer They stripped it and found that the injector pump was rusted in certain parts and did not fuction properly (that was the loss of power). The strip and replacement pump cost a fortune.
If you can afford to take the chance on the cost if you miss something then go for it. You might get away with it after all!!

Well, so far, so good.

The engine is running very happily at present. I will continue changing the oil frequently over the next couple of weeks, and will look at the injector pump externals and the fuel tank (which does not seem to have got salt into it)

The alternator is, inevitably, having a rewind. It does make one wonder about the cost of "marine" alternators compared to vehicle ones - Hitachi are, I gather, espescially pricey!
