Just a few comments regarding the use of Glow Plugs..
I vaguely recall reading in a diesel book, that modern designs of the heads
and injectors on a diesel do not require glow plugs.
I had Caterpiller 3208Ts on a trawler (320 HP) and they did not have glow
plugs.
I never had any problems starting them, even in below freezing weather. They
always started promptly on the 1st engine rotation.
This CAT design was essentially the same as the design used on big trucks,
earth movers, etc
I have also read (somewhere, not sure where) that if an engine has a glow
plug, you should hold it depressed as suggested by the manual, but should
not have it depressed when starting. The reason given was that the extra
stress on the red hot glow plug during start up will reduce the lifetime of
the glow plug.
Does anyone have any experience with that??

My Yanmar 2GM dont have them and dont need them. In south Carolina
where the temp is always higher than my age they start up with no
problems.

I have a 1981 3QM30. Purrs like a kitten.
No glow plug. Start up cold just fine. Just a few more cranks. Before
this engine I thought all diesels had glow plugs.
What gives?

David,
The glow plugs are only needed when the engine is cold. I hold that glow
plug button for at least 30secs. Rule of Thumb: Take 100, subtract the
water temp and hold it for those seconds, and you should be good for a
first
try. If the water is 40 F, hold the button for 60 seconds. If the water
is
70, hold for 30 seconds. Count 1000 one, 1000 two and so on, or use a
watch.
Once the engine starts and has warmed up, we go sailing, shutdown the
engine
and later I restart the engine without needing glowplugs.

I have only had a few tries at starting the M430 engine on my new boat,
and
I have been told several different stories. One person said to hold the
glow plug button for 5-10 seconds and then start. Another said 30 seconds
on the glow plug and then leave the button pushed while also pushing the
starter. The latter worked when I was first starting the engine after the
winter while plugged into shore power. Yesterday I started it for the
first
time without shore power and found that the starter did not kick at all if
I
started while also holding the glow plug button. Started find when I let
go
the glow plug button. What is the "normal" starting procedure with a cold
engine in cool weather. Warm weather? Warm engine? Thanks- Dave
