For a new M3-20B, the Universal Operator's Manual gives a table that
says hold the preheat switch for approx 10 sec if temperature is 41F/5C
or higher, 15 sec if temperature is 41F-23F/5C- -5C, and 20 sec if temp
below 23F/-5C. 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.

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
