It may be because these engines are not designed to start in really cold conditions. Inboard marine engines are seldom asked to start at much below the freezing point.

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 F.

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.

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?
