My 3JH2E starts easily at idle. I didn't know about adjusting the throttle to 
start.

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.

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.

Running it at the slip in gear would provide some load to the engine and be
more beneficial.  We usually have a 45 to 60 minute motor to the race
course, which helps keep the engine in top shape.  I usually set it at
2,800 rpm and keep it there.  Always idle it for a few minutes before
shutdown too.  This will help cool down the internal parts before you shut
it down.

Re: Stus-List yanmar diesel

2016-10-06 Thread Josh Muckley via CnC-List 
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.

have to agree with the dirty injector route. Also these engines need to get

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

2016-10-06 Thread Hoyt, Mike via CnC-List 
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.  Really hastens the bleeding process

I think the tank cleaning and fresh fuel should be done regardless.  I did 
that, it helped, the old fuel was the color of weak coffee, the new was nearly 
clear.

On the other hand, a clogged exhaust elbow (or any other restriction in the 
exhaust) will result in a loss of power under load and a lot more black smoke.  
Since you said it runs clean when it finally does start I don't think that's 
your problem.

Hello experts,

I wonder if you can help me with any suggestions. I have a C with a 3GM30 
F. This motor runs well and smoothly, water circulates, no smoke. Recently it 
has been taking more and more revolutions to get it started. When it is turning 
over there does not appear to be anything going on, but when it starts its 
immediately smooth and normal (no coughing and spluttering).

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. The fact that it seems to 
start with all 3 cylinders suggests that the leak is before the injector pump.

I cannot see any fuel leaking out at the supply pump or filter, so I'm 
wondering if anyone can suggest where I should start looking? Or what might 
cause this and not show fuel leaking or spraying out? I'd like to introduce 
some method into my troubleshooting!

Thanks and regards

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)

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.

Hello experts,
I wonder if you can help me with any suggestions. I have a C with a 3GM30 
F. This motor runs well and smoothly, water circulates, no smoke. Recently it 
has been taking more and more revolutions to get it started. When it is turning 
over there does not appear to be anything going on, but when it starts its 
immediately smooth and normal (no coughing and spluttering).
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. The fact that it seems to 
start with all 3 cylinders suggests that the leak is before the injector pump.
I cannot see any fuel leaking out at the supply pump or filter, so I'm 
wondering if anyone can suggest where I should start looking? Or what might 
cause this and not show fuel leaking or spraying out? I'd like to introduce 
some method into my troubleshooting!

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...

I'm experiencing the same issue with my 1GM10. I'm suspecting an air leak in 
the line. My trouble shooting thus far has only been replacing the fuel filter. 
I'm anxious to hear suggestions too.

Stus-List yanmar diesel

2016-10-05 Thread Michael Jones via CnC-List 
Hello experts,

I wonder if you can help me with any suggestions. I have a C with a 3GM30 
F. This motor runs well and smoothly, water circulates, no smoke. Recently it 
has been taking more and more revolutions to get it started. When it is turning 
over there does not appear to be anything going on, but when it starts its 
immediately smooth and normal (no coughing and spluttering).

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. The fact that it seems to 
start with all 3 cylinders suggests that the leak is before the injector pump.

I cannot see any fuel leaking out at the supply pump or filter, so I'm 
wondering if anyone can suggest where I should start looking? Or what might 
cause this and not show fuel leaking or spraying out? I'd like to introduce 
some method into my troubleshooting!

Thanks and regards
