Re: Stus-List Yanmar diesel
When I replaced my injector pump, and after extensive bleeding. The engine was extremely difficult to start. The throttle cable was disconnected. Hooked it up. Moved throttle to 3/4 open. Started almost instantly. I always start at between 1/2 and 3/4 throttle, then pull it bact to idle.

Re: Stus-List Yanmar diesel
I have/had a similar issue. 3GM30 Left 1 week or longer it was hard to start. When it did finally start it first started to fire on 1 or 2 cylinders. Lots of black smoke etc after. Then runs smooth. The less days between starts easier starts. Even 1 day would be an instant start. On Oct 5 and the time before Sept 21 I had instant start. 14 days and the time before was longer. I was really surprised by it especially the 5th as the temp was around 20C. My battery isnt the issue. I think this behavior started after I changed filters and bled the lines but not positive. It was done in 2015. One of last sails before this stopped was a hard sail in gusts 20k true. Close hauled and heeled over N2 and full main. Not sure whats going on. Thinking I stirred things up in the tank.

The black smoke may indicate excessive carbon buildup. If you don't have three hours to run it is, next time you bring her in while the engine is still running out it in neutral and run it up to 90% of max RPM for about 5 minutes.

Re: Stus-List yanmar diesel
A machinist friend of mine told me that his recommendation is to run it for 3 hours every time. He had 3 one hour goals. IIRC the first hour was to drive the moisture out of the oil, the second hour drives the moisture out of the engine, and only during the third hour do you really start burning of any carbon build up. It seems that moisture is the biggest problem. Moisture causes corrosion and accumulates carbon. No moisture, no problems. In the winter I keep the moisture out by running a block heater. I presume that frequent enough engine ops during the summer is sufficient... Then again maybe not.

Re: Stus-List yanmar diesel
I have the same issue with my 2Qm. I've learned to live with it. I suspect it's battery. My boat sits on the hard all winter (Nov - May). I put a freshly charged battery in it, straight from my garage charging station to the boat and it fires within a crank or maybe two if it's ony 5 or 6 degrees (40 F ish). If it were a fuel leak, the 7 months would definitely drained the lines. So fuel is available and getting there. Fresh battery starts the 1979 old beast with ease. Later in the season, the battery is likely not 100% charged and it takes longer. Maybe more resistance from old oil too...although 5 months of oil use shouldn't be too bad. Easy to test. Charge the battery well...then hit the button...if it takes less time you don't have to tear down anything. If it does not then have fun tearing the beastie down.

Re: Stus-List yanmar diesel
The described problem sounds very similar to that on our 3GM30F. We have gone through 4 full tanks of fuel this year so it is not stale fuel The fuel lift pump was replaced in the fall. The racor filter was changed as was the engine fuel filter The Injector pump was rebuilt in the Spring When starting in colder weather (and I seem to recall in wet weather sometimes) it cranks longer and then it seems two cylinders catch before the third. Runs flawlessly one it starts. When it starts after a long crank an initial cloud of black smoke comes out and then all is fine. When a warm start it fires up instantly My mechanic calls that “old yanmar” and says it is normal. It is our intention to remove all three injectors this fall and have them rebuilt as well For priming we have installed a fuel squeeze blub before the lift pump and after the Racor.

Re: Stus-List yanmar diesel
Michael , Before you start tearing things apart, check to see that your fuel feed line from the tank to the fuel pump is not obstructed. There is usually a small screen on the end of the line that terminates in the tank that clogs up and can restrict fuel flow from the tank to the pump. This is a common problem usually solved by blowing air through the line from the pump end back into the tank. I had a similar problem and fortunately someone on the list suggested this procedure to me. It worked.

Re: Stus-List yanmar diesel
The 2QM15 I had got progressively harder to start as it got colder out (30 - 40 secconds of cranking before it would fire), but would run fine once it got going and start again instantly several hours later. The engine had lots of hours so I was concerned the engine was going to need a re-build. I tried several things, with little effect, and then took the injectors out, took them to a shop that replaced the tips. It made a huge difference. In the summer it would start to fire almost instantly, and in 10 or so in the fall. Cranking RPM is an important part of the mix. Before looking at the fuel system, I'd make sure your cables are good. Test with a volt meter connected to the positive lug on the starter motor and the engine ground. Have someone turn it over. The voltage will drop by 1 to 1.5 v, if any more then start inspecting and cleaning connections on both positive and negative cables and the battery terminals. If the starter is a bit sluggish, and there is very little or no voltage drop when you turn it over, then the starter itself should go to an auto electric shop for brushes or solenoid replacement. (IMHO it better to rebuild original than roll the dice with Nappa replacement) Eric On Wed, Oct 5, 2016 at 8:16 PM, Josh Muckley via CnC-List < cnc-list@cnc-list.com> wrote: > No glow plugs on these engines.

Re: Stus-List yanmar diesel
How many hours on your engine? How are you filters? Does it have glow plugs, a bad glow plug will cause hard starting. Dirty injectors will also cause this, but I think there would be more issues, like poor idle. With the smooth running agter start I don't think it is fuel related.

Re: Stus-List yanmar diesel
I would check the compression and the injectors. You can do simple injector tests by installing them upside down so they spray up. If the spray pattern isn't even and a fine cone then they need cleaned. You could clean them yourself. While you have them out you have a perfect opportunity to check the compression. Compression should match between cylinders +/-25ish and be ~400psi. Inspect and clean the precombustion chambers below the injectors. Reassemble and see if it starts any better. If not I might consider getting the injectors pop tested. If air is getting into the system a strip of paper towel tied around culprit fittings will provide proof in short order. Then again a back leakage of the various check valves would be kept internal and be very difficult to troubleshoot. You could just go sailing...

This leads me to think that there must be a leak in the fuel system which is allowing the fuel to drain back out of the injectors.
