hi, i've just bought a boat and it's out of the water at the moment, it's a invicta 26 with a yanmar engine a couple of years old, yesterday i tried starting the engine just to see if it would work and intended to turn it off straight away as the boats out of the water it wouldn't be able to cool etc.

I realise this was a mistake as i know nothing yet about boat engines, or any engine come-to-that, i'm keen to learn though and am handy at most other things.

Anyway, i started the engine and it started fine, then i though ok i'll turn it off, i turned the key to off but nothing happened it kept running, not knowing any other way to stop the engine i shut off the fuel supply, the engine then shut off, then i noticed a little smoke coming from the engine and a burning smell, i couldn't see where the smoke was coming from but it cleared after about a minute.

My questions are:

Have i broke my engine?
Does anyone know where i can get a good book on a 1GM
How do I stop the engine, should it turn off when i turn the key?

Thanks so much, sorry i've waffled on a bit but i've been worried about this all night.

Cheers Stu
 
There will be a stop lever somewhere around the injection pump. But first you'll need to find the injection pump!
You have probably burned out the water pump impeller.
These are service items and it is not a serious problem. You will need to fit a new one and ensure all the bits of the old one are accounted for as they could block the waterways.
Other than that, welcome to the steep learning curve of boat ownership and enjoy!!!
 
It will not stop on the key you need to pull the stop cable or work the stop lever on the engine.
Depending how hot it got you may have damaged it, or cooked the water pump impeller.
The burning small may have come from the rubber exhaust pipe, you need to check it.
 
No,Probably not.The way to shut the engine off is by pulling on the fuel cut off that goes to the injection pump.The handle should be on the panel.What you probably did was to destroy the water pump impeller and burn the rubber exhaust hose.Those will have to be replaced.
By turning the key off with the engine still running you also risk burning the alternator's diodes.Next time you have it running make sure the batteries are being charged.If not just take the alternator to a shop and they fix it for you.
A very good workshop manual can be bought from Yanmar but that's mainly mechanical.An owners manual is available probably from them as well.
 
thanks, i've read about impella replacement and have a spare, i really need a yanmar book.

The engine was only running about 30 seconds and no warning lights sounded so hopefully it's not damaged!

Thanks for replies

It would also be worth getting yourself clued up a bit about engines, and This Link will take you to the RYA diesel engine book. Might be worth trying to get hold of one of the free CD's they sent out a while back with magazines. At least that will give you a basic understanding of how they work and how to fix them if things go wrong at sea
 
No i turned the ignition key to off not the battery switch, the battery switch was still on the engine battery. Sureley this wouldn't damage the alternator. I know from day-skipper course not to turn battery switch to off while engine is running.
 
Point made - post deleted - TRFM before experimenting further...... /forums/images/graemlins/grin.gif

or ask on here beforehand - could save you many beer tokens.

ok, so i made a mistake, it wasn't life threatening, i apreciate how dangerous the sea is and i'll learn by it, probably the hard expensive way.

Thanks for all those that responded to me as if i were human, everyone has to start somewhere, i probably won't post again.

Don't give up, most of us are human /forums/images/graemlins/wink.gif
If it was only 30 sec's it's very dountfull it got hot enough to do any major damage & it would have been sensible to have changed the impellor anyway.
Try a wanted add (free) on these forums for a manual.
Might be worth asking around your local boatyard to get someone to give your engine a quick once over as well.
Good luck with your project
 
Where abouts are you, i'm sure there maybe someone local who could give you 1/2 an hour of advice and point you in the right direction.
 
If it really was only 30 seconds the metal parts will hardly have got warm, and the bores and pistons will have had some oil splashing about, so you shouldn't worry on that score. Some drag racers don't run coolant and they produce a tad more power.
Many diesel plant engines are aircooled and whilst they are designed that way it still takes a while to get them up to operating temperature.

I would suggest that you may have been lucky. Impellor is bound to be jerked, but the other things may or may not.

A good idea may be to find some other boat owner with a similar motor and quiz them. There's only so much you can take in from books and the written word can make things sound very daunting.

Erm, so can posting on here. However you do get a good range of replies. Just pick out the ones that seem appropriate.
 
I'm on the Isle of Wight, i've contacted a marine engineer this morning who is going to take a look at it, i want to get to know the engine really well too though so i'll be looking over his shoulder, i've just bought a yanmar book off amazon too.

I have done the comp crew and day-skipper so should have known better.

Thanks again

Stu
 
Don't be daft. Advice given was helpful, though possibly a little sharp from some. Mr Smiley (one of these /forums/images/graemlins/cool.gif /forums/images/graemlins/wink.gif ) is not available to convey the 'just trying to help' emotion, the RYA course will give a general understanding of ALL diesel engines, not just the one. And they all have the same basics, which is where you've gone wrong here. Once you know the basic stuff, the rest comes easy. Try finding one of the free DVD's, failing that, get in touch and I'll send one (I ended up with two)

You should check for the damage mentioned, although I've survived all these things without doing any damage worth a mention. some starter switches even allow the key to be removed in the "run" position so it can't be turned off by accident. The smoke and smell is most likely to be the ehaust hose getting too hot, but unless that's particularly old it may yet survive, albeit needing the clamps tightening to take up the slight deformation of the surface. Once you've found the stop lever (usually a t-handle on the instrument panel) try running with a bucket of water to feed the water pump. Take the inlet hose off the seaciock and put it in the bucket, start up and look immediately for water sploshing out of the exhaust. If there is water coming out, then the impeller is working. Not so easy to check the alternator output, as it is possible to take out the diode which is used to indicate the charge status. Find someone in your local club who is familiar with Yanamars and get them to give you a hand!

Out all day yesterday, bit breezy to say the least, but spent most of the day with the lump turned off so not a bad day. Gale warning out for the area just North of where we were sailing so a little lively on the return leg.
