Hi David, I see you've gotten good advice already. Our boat has that engine, the M4-30 and Glowplugs are a good thing. They help start a cold engine. I've heard stories of Yanmar owners using a hair dryer on an engine to get it to start. I usually hold the glowplug button for 30 seconds or more, the first time before trying the start button separately. I don't think you can overheat the engine, but it uses battery power. I make sure the shifter is in neutral and set the throttle part way open.
There is a glow plug, for each of four cylinders. If one plug is cold, it will make starting a little more difficult. You can verify all the glow plugs work by a simple check. When the engine is cold, hold the glow plug button for 30 to 45 seconds and then open the engine box and feel for a warm spot near each glowplug on the engine. If they all feel equally warm, they are perfect. If one is cold, you need to check electrical connection and maybe replace the glow plug. On our engine, there is an electric booster fuel pump. When you turn the key, the gages are powered and the fuel pump starts ticking. Listen for that sound before trying to start. This is also a good thing. We found when it stopped working, due to a green corroded ground connection, we could run the engine fine up to half speed. The engine has a return hose, and I think the pump may negate needing to bleed air from injectors. FYI, I had our starter rebuilt by a car starter rebuilder, $75 for new solenoid, bearings, brushes.

With Universal-supplied panels the preheat switch has to be pressed for the starter button to work, and it (the preheat button) has to be held down until oil pressure builds up, other wise the engine will stop. This was also the same info given in the operators manual for an older 20B-2, which I think was about your engine's vintage, though some engines did not have the oil pressure switch feature.

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?
