After reading several threads on the 2gm...has anyone found an easy way to cold-start a 2GM??? Yes, I'd checked all of the filters, and, they are clean. Once the engine is warm, it starts right up. There is no glow-plug on this engine...a friend of mine just suggested a very short squirt of WD40 in the air intake, but, I'm afraid of blowing up the boat (he DID go on to say to stay the hell away from ether). The owners manual suggests giving it about 1/2 fuel, and, once it starts, setting the throttle to idle. Also, I tend to keep my finger on the starter for quite awhile until it catches...any threat to damage by doing this...thanks in advance...

stay away from the WD40 too.
Tim: There have been posts about WD40, the advice was to stay away from it unless you want a new engine. Do you rev your engine too about 2000 rpm and pull the kill switch when shutting her down. If you don't you may want to try this too. Also are you using a multi-grade oil? If not this may add to your starting troubles. During the off season you may want to have your injectors checked. Be careful starting your engine an holding down on the starter button too long. The is no way for the water to get pushed out of the engine if you just keep cranking. You may want to consider shutting off the raw water intake until the engine starts. Once you engine fires you can open the sea cock.

Steve D. is right on...
...as usual. Also, holding the starter on too long is hard on the starter. The 1/2 throttle method always works for me.

Cold start
I agree with the other posts about starting additives not being good for the engine. Yanmar ( and other diesel manufacturers ) recommends a slow rev shutoff. It was explained to me a high rev shutoff allows excess fuel to wash down the cylinder lubrication.

Rev before shutting down!
David: per the Yanmar service manual (pg 13-11) STOPPING "(2) Before stopping, temporarily raise the speed to the rated speed to blow out residue in the cylinders. The stop the engine by pulling the engine stop lever to cut the fuel."

Thanks Steve...
I don't think I would have seriously considered spaying anything in the air intake. I'm guessing that the revving suggestion might work. If the injectors were faulty, would not the engine run bad? Thanks again.......Steve D, Steve O, and David

Another thing you can try...
If you're having problems with a cold start after the engine has been sitting for a few days you might try decompressing it, spinning it for a few seconds and then recompressing it. This gets the juices flowing and starts warming up the cylinders. Be sure you don't back seawater up the elbow though. Diesels tend to run rough when first started, especially when cold. Stay away from sprays, 1/2 throttle works pretty well for me, sometimes I use the above procedure if it has trouble.

Stop
Steve you are right as per manual. But that does not preclude lowering the RPMs immediately prior to stopping. Read further. I was referring to Section 2-4.2(2) If the engine is stopped immediately after full-load operation, the temperature of each part will rise suddenly, leading to trouble. I think the above section is why it is recommended to run the engine in neutral at 1000 rpm prior to stopping.

Did not include the cool down instructions.
David: I did not include the cool down instructions. The step before this indicated that you should let the engine idle for approx. 5 minutes before the actual shut down. This step is to prevent heat saturation as you have pointed out. My advice was for Tim's problem with cold starting only. I thought that he may have some residual fuel in the cylinders which may be causing a flooding condition, thus making for a difficult cold start.

How to decompress
First of all...these are all great suggestions, as, I've only just purchased my 29.5, and, am not used to a 2GM. I had a 1GM on my old 27, and, never, ever, had starting problems. As to Miles suggestion about decompressing, do I push the little lever on top of the fuel filter...sorry, but, I'm not all that familiar with diesel engines. Thanks again for all of the suggestions...I've printed them out and have added them to my owners manual.

Hi Tim...
The decompression lever is a little switch on top of the head in the same area as the injectors. There will be one for each cylinder. When you flip it up there is no pressure in the cylinder and the engine is very easy to turn over but it will never actually start. Cranking it briefly in this condition should help. Then flip the levers back down and crank again to start. This is also a good trick if you ever have a low battery too, you can get the engine spinning fast easily and then recompress it while it's spinning and with luck it will start.

have it checked
my 2GM starts in cold weather and may stall if I don't turn up the rpm's but always starts cold or warm ,It could be alot of different things ,does it crank the same speed warm or cold if not check the oil I use 15-45 shell ,also check for water or air in the fuel,if it does'nt start, don't hold down the start button too long, wait a few minutes in between trying to start it.

how cold is it?
I have been following this post with great interest and have seen great answers. I have a question for you. Just how cold are we talking about temperature or are we talking about "cold" as the engine has not been run in a week?

Help!
Hello, I just purchased a 1977 Hunter 27. It has a yanmar engine. I tried to start it but it will not start. And yes, I already made the mistake of using Ether. oops! Any way, the fuel is old I am sure! I will have to empty it some how and add new fuel. But so far, she will not start. I put the engine in neutral and placed the throttle about half way. Then, I turned the key to start the engine. She turns over nice but it will not fire. If you can help me by providing me some tips, I would greatly appreciate it. I am very new to the Hunter 27. I, however, have been sailing for 30 years. So, I know quite a bit about sailing and seamanship. But I know nothing of internal diesel motors. I read the replies that you have written to Tim's Post but that is it. Please help! Skipper (Skipper of the BayBee) P.S. Go check out my web site for South Coast Yachts if you find time! See Link....
