White smoke.

[lokas0506]

Yanmar 1gm10. When starting a few small puffs of smoke will come out around starting motor smell of burnt electricity , didn't have an anode for 5 weeks now a wire conected to a - and a spoon at the end of it :-)

We get a little puff of white on start up also but I thought it was just steam until the water pump">raw water pump got water into the exhaust. In our case I only notice it after she has been sitting for a while and if I go for a sail then start the 2GMF to come back in I don't get the puff.

Sometimes diesel engines briefly emit a white smoke, which is finely atomized raw fuel and water vapour, while starting, especially when cold. This is not abnormal.

Puffs of white smoke coming out around the starting motor and smell of burnt electricity, doesn't sound good. New starter, check wiring, replace anode asap. You can really ruin your prop and struts.

Sounds like your starter is full of greasy saltwater.

I don't get the part about the spoon?

Smoke around the starter and electric smell is NOT normal and could be a risk of overheating or even a fire. Most likely cause it corrosion or loose connection on the wiring to the starter or solenoid.

First step: remove the wires going to the starter and solenoid, inspect for broken wires or loose connectors, clean and replace. When replacing be sure to snug up well.

Thanks guys for response.
The spoon i observed started taking an anodes color once left for longer while on deck so I thought why not connect to the minus on the engine via a copper wire and drop it in the water so anyway if not the spoon then the wire will start getting consumed...
How long do I have before before minor effects fr op m lack of anode days weeks months ...
Well I suppose sooner or later will have to buy a new starter motor.
Am not sure if the starter motor got soaked with oily water ...
I will keep observing ...
One theory is that a short circuit and the coils of copper are getting burned ( the battery might been low) since I had the starter motor problems cranking the engine ...

It might be some oxidiser (?) Process... So definitely an anode or a substitute till I get a chance to fix one permanently.
Any ideas on substitute anode and issue solutions welcome and appreciated

They make a large zinc fish looking thing that you hang over the side in the water and has a wire to connect to the prop shaft. Or make up one till you can get your zinc replaced. If your boat is not properly zinced your underwater bronze parts will weaking and loose strength. I've seen props and struts fall apart.

Lokas, The wiring harness plugs & sockets will show all sorts of troubles. The easy test is to use a wire or switch to operate the starter solenoid (starter relay in Yanmar speak) the engine end to crank the engine. There are many reports on the plug & socket issues with this series of engines as they age & the strange symptoms that relate. Measure the voltage at the solenoid terminal compared with the starter battery terminal voltage while cranking would be easy to do.

Regards

Thanks Bill. First need a multimeter but everyone has one but me :-)

I recorded the whole cranking process

the stall in the middle of starting tells me the starter is either on it's last legs or that the electrical connections between it and the battery are in rough shape causing much higher current than normal, causing more heat in the windings, theryby releasing the magical smoke, placing the starter onto it's last legs.

[lokas0506]

Could this be caused by lack of anode ? Solutions ... Check the connection between ( what are the signs of electrical in bad shape) ... Well I suppose I 'll start looking for cranking handle !

[Sailmonkey]

The anodes are to protect the metal items on contact with the sea water. A missing anode will not cause this, however this may cause an anode to go missing if there is a ground fault.

All electrical connections need to be clean and tight. From the battery through all switches and back to the battery. Any one if these can cause the problem you're seeing.

My gut tells me that you've got a grounding issue more than a supply problem.
